Hello, I haven't posted pics of my car here so figured I should probably get around to it.
Bought it last Jun/July. Overall in very good shape. Documentation that came with it suggests its a 368 making 550hp. I do plan to determine whether or not that is accurate, but boy does it feel like its true! First time owning a 'fun' car, and it has been a blast so far. I've taken it to a couple car shows and done a few events with some of the local corvette clubs. Originally I was looking at C3 Corvettes, but shied away because I was afraid of dealing with frame rust. WAZOO has been great as well. That really is a fantastic group of people. I have almost no information on previous owners. Dealer told me the last owner had passed away. I did recently find an old receipt stashed in a very odd spot that has the name Tom Wong from a Sears in Annapolis, MD. Perhaps that name rings a bell with someone here? Here is picking it up from the dealership with my girlfriend. It was in desperate need of a wash! https://zr1.net/forum/attachment.php...1&d=1674198765 Door sill cover that is on both driver and passenger sides. https://zr1.net/forum/attachment.php...1&d=1674199057 First car show! https://zr1.net/forum/attachment.php...1&d=1674198765 This was at an annual picnic outing with North Virginia Corvette Club and Old Dominion Corvette Club. I am a member of both. On this particular outing I was the only C4! https://zr1.net/forum/attachment.php...1&d=1674198765 Recent pic after waxing it. Paint is not perfect, but it does clean up well. I plan to have two of my panels repainted soon to fix the most glaring issues. https://zr1.net/forum/attachment.php...1&d=1674199472 |
Re: 1990 #2659

Re: 1990 #2659
So the car is currently getting the Haibeck treatment. I got a message from him last Friday that my spot had opened up. That night I turned in early, got up at 1AM and drove about 11.5 hours to get there, encountering a blizzard as I came through Indiana. There was a little bit of a pucker factor forming as I saw snow starting to build on the road but I got past it before it became a real concern. Car drove great, but by the end I was really feeling all the pressure points on that seat haha!
It is said often on these forums, but I must echo the sentiment as well: He is truly a master at his craft. With one short test drive and simply observing what was under the hood he was rattling off a whole list of items he was seeing that I had no idea about. Since working on the car he has continued to find things of interest. Top of that list is that my engine is not original to my car. It is from '91 #1981, and was built out by Lingenfelter. It raises so many questions for me that I know I will never have answered. I'm just going to assume that at some point the original motor blew up and was replaced by this one. Absolutely no timeframe on when that could have happened. Other fun facts that are much more tame: My Hurst short throw shifter is actually a B&M Shifter with a Hurst knob on it. "10% shorter throw than a Hurst" according to Marc. Headers are the original offering from Watson Engineering, which produced the first aftermarket headers for the ZR-1, primarily meant for race teams. I have the dubious honor of presenting Marc with a failure he has never seen before. The switch for my fog lights failed, only activating for as long as the button was depressed. Years prior someone had bought a rebuilt ECU for the car. Marc was the person that had rebuilt it. My car was listed in his copy of the 2001 registry, owned at the time by a Paul Brown of Pittsford, NY My wheels are actual GM A-Molds and not aftermarket. I also brought to Marc's attention that the material on the driver side door armrest is slightly different than the passenger side. The passenger side has a more leathery look to it while the driver side is more of a mat plastic. He claimed he had never noticed that, and double checked on another car in the garage that was all original to verify it wasn't something that had been changed. It did indeed come from the factory like that. My 0.0001% contribution to his knowledge of the ZR1. |
Re: 1990 #2659
Glad you made it through the snow Zack, did the same a few years ago and was not fun. Glad you are getting the Haibeck treatment, you will love the way the car is returned. Very interesting information as well, sure somebody will chime in about the previous owner Paul Brown. See you soon.

Re: 1990 #2659
I too am a new owner of a ZR-1, a 1993 that I have had for 3 weeks now. You mentioned a receipt with the name Tom Wong. Probably more than one Tom but the Tom Wong I know is a very good GM tuner located in Vancouver, Washington. Enjoy your car. Brian

The car is back from Haibeck's. Marc works evenings on Fridays and that allowed me to catch a late flight and pick up the car close to midnight. I was not entirely unsurprised by that, we have actually exchanged a number of emails in the wee hours of the morning. I can appreciate a fellow night owl.
https://www.zr1.net/forum/attachment...1&d=1681104637 The car feels great. Worlds away from what it did prior. The combination of new shocks and frame stiffener goes a long way to make for a more comfortable and enjoyable ride, and the rebalanced clutch has removed the concern of imminent disintegration at high RPMs. https://www.zr1.net/forum/attachment...1&d=1681104637 A bit of everything was touched during this visit, but the big things are as follows: DeWitts double row radiator Frame Stiffener Kit Fidanza Aluminum Flywheel New Shocks (A mishap with the supplier actually means I only have 3 new shocks, 4th to be shipped down. Potential WAZOO maintenance day item I suppose) Rebalanced Clutch Dyno Tuned Speedometer Correction for 3.91 gearing Minimum Dimness for the gauge cluster to ~20% Along with a number of smaller items that Marc discovered along the way. I had made a comment that I wasn't entirely happy with how my shifter boot just falls loose down the stick instead being mounted up and he figured out a way to rig it up. He really goes the extra mile. Maybe the one less than happy item from this whole thing was the Dyno numbers and what they mean. Marc got it clocked in at 509hp, and while a great result it does indicate the engine is not as powerful as I had thought. A potential upgrade I will have to consider for the future. In the meantime I will leave my door sill protectors on as a historical artifact of the car. https://www.zr1.net/forum/attachment...1&d=1681104637 Today I washed and waxed it. The exhaust tips were straight black after having traveled ~1500 miles (somewhat visible in the photo above), and they received a well deserved polish. Lots of road grime to wash off, but I am glad to have it back. The weather has been so nice recently that I was sorely missing the car. https://www.zr1.net/forum/attachment...1&d=1681104637 |

I've had the car at a couple shows recently. I get a huge kick out of going to them. I probably need to step up my game and get a poster made for it.
First was 'Finish the Race Car Show' in April. It was a pretty huge turnout, probably over 200 cars. The minister for the church has C4, C6, and C7 ZR-1s. Him and his wife are definitely car people! https://www.zr1.net/forum/attachment...1&d=1685134763 https://www.zr1.net/forum/attachment...1&d=1685134763 Part of this show is an exhaust competition called 'Rev Your Rumble,' They take a decibel meter and hold it to your exhaust and see who has the loudest car. I took third place overall, coming in at 117.6 dB Here is a clip of me starting off the competition: https://www.facebook.com/718355433/v...6698597338434/ (if I have the privacy settings wrong and you cannot view it let me know) and a pic from after: https://www.zr1.net/forum/attachment...1&d=1685135102 The second show, 'LHS Car Show for the Special Olympics 2023,' was right across the street from my house in Bealeton. Probably 100 to 150 cars turned out. Proximity to home made this feel much more laid back since I didn't need to clean off road grime when I got there :dancing https://www.zr1.net/forum/attachment...1&d=1685134763 Not sure when the next show will be. My schedule has me traveling a lot over the next 2 months. |
Re: 1990 #2659
Looking good Zach, way to represent. I have seen the Minister and his cars at Carlisle, impressive!

Re: 1990 #2659
Your car sounds lovely!! Very nice pics and good level of cars. Thanks to share.

Thanks. The video doesn't do justice to how loud it actually is. If you pay attention to the people on the right side of the video you can see some of them wincing and plugging their ears or making faces. It really catches you off guard because at idle it doesn't sound like it will scream so hard. I think its a bit raspy, not quite as full bodied of a sound as I my ideal would be. I've been told by one of my older friends I need to put some cherry bombs on it, but at that point I may as well just straight pipe it and make my neighbors hate life. I actually quite enjoy how civilized it is under 3500 RPMs, and the Corsa tips are by far my favorite look. There were ~15 cars in that competition. Lots of scatpacks and mustangs ringing in between 110 dB and 115 dB. Also a couple of Hondas with fart cans that sounded extremely quiet after all the muscle roared. The loudest was a lamborghini modded to spit fire, it hit 119.1 dB. The C3 next to me was second loudest at 118.3 dB, really great sounding car. Sent from my iPhone using Tapatalk |
Re: 1990 #2659
I saw the people you talk about... Good remedy for build up of ear wax :D:D
I agree with you that Corsa rear look is amazing for our cars and the sound is one of my favorites My unit has OBX headers and complete exhaust line ("similar" to Corsa look but with soft noise) and I'm completely satisfied with noise. Quiet until 3.000 rpm and acceptably screamy over 3.000 rpm. I never checked my noise level. I should try... |

More car shows, more enjoyment.
A view I am quite fond of: https://www.zr1.net/forum/attachment...1&d=1693865781 I have found a very small hole in a section of plastic tubing in one of the refrigerant lines. At some point I need to drain it and replace the section. I actually think this may be the culprit of some of my recent engine temp concerns. As the fluid leaks the AC system must work harder to compensate, which dumps more heat into the engine. Running without the AC on basically eliminates my problems. Once fixed I am hoping the AC won't affect my engine temps quite as drastically. I am a member of Old Dominion Corvette Club as they host a bunch of local-ish events to me. We took part of their 34th Annual All Corvette Cruise-In. Despite being scorching out it was a good time. https://www.zr1.net/forum/attachment...1&d=1693865781 Of course we were at Carlisle, too. Great to meet everyone. We didn't shine her up until the last day on account of the weather. Phil Wasinger allowed me to borrow his Tech-1A to try and troubleshoot an issue I have been experiencing on cold start. https://www.zr1.net/forum/attachment...1&d=1693865781 Yesterday the weather was too nice to ignore. We popped the top and went for a ride through Shenandoah. Nice drive with great views. https://www.zr1.net/forum/attachment...1&d=1693865781 |
Re: 1990 #2659
Looking good Zach! We replaced my coils and now my stumble is gone. While we were there, removed the starter and replaced it with a rebuilt one. It was showing lots of signs that we made the change just in time.

What symptoms were you seeing? My engine stumbles the first time i lift off the gas after a cold start. Sometimes that stalls it. It'll start right up afterward and not do that again until the engine completely cools down and is cold again. Sent from my iPhone using Tapatalk |
Re: 1990 #2659
Anytime over 3000 RPM it would stumble. Also while going down the highway in 6th gear at 70 MPH if I hit the throttle it would stumble. We believe one of the coils was on the way out and by changing all 4 it solved the problem. Now I have all the horses running!

Re: 1990 #2659
That will need to wait until Wazoo maintenance day and Ricky driving down from NJ. No rush on that, others need to get their cars running right first.

Re: 1990 #2659
Have you already been thinking about what you will do for speedometer correction? Or did you already have a correction box that you can adjust? I think it will be hard to find the right correction gear for the 3.73 unless you already have one.

Re: 1990 #2659
Getting the correction gears for any ratio is not a problem

Its been a busy 6 months!
I had the car at a show down near Culpeper in November at Brandy Station Fire Department. https://www.zr1.net/forum/attachment...1&d=1711436002 At this show I ran into someone I knew from an Archery club I am a member of. Never knew he was big into cars. We got to talking, and I shared with him some of my woes when it came to my wheels. https://www.zr1.net/forum/attachment...1&d=1711436002 Ever since I bought the car the wheels have been extremely oxidized. I had tried a number of wheel cleaners but nothing ever worked to clean them up. He had an idea, and as it turns out he recently moved and now lives extremely close to me. He turned me on to Speedy All Metal Polish. With a couple drill-attached buffers it made pretty quick work of it all. Far and away better than anything I had tried previously. https://www.zr1.net/forum/attachment...1&d=1711436002 At some point I will remove the wheels and get inside the barrel as well, and probably ceramic coat them. The big lesson though, is I really need to get a face shield before I do that again! https://www.zr1.net/forum/attachment...1&d=1711436612 It looked like I was wearing eyeliner for a week. The clean wheels really make the car look better. It really pops. At the Remington car show a week or two later a small boy pointed at the wheels at told his dad they were super shiny. Definitely made it worth the effort. https://www.zr1.net/forum/attachment...1&d=1711436002 This doesn't nearly cover everything, more to come! |
Re: 1990 #2659
Awesome job on the wheels, the car is loving you as the owner!

Towards the end of December I approached Dempsey Anderson at Evolution Motorsport Engineering about his Dragonheart package.
The car already had a fair bit done previously. In fact the plenum and IHS were already siamesed. https://www.zr1.net/forum/attachment...1&d=1711510723 However, it was an older port job that didn't quite compare to what is done today. Some of the curves in the runners were a bit rough. Port matching left a bit to be desired. While it certainly performed well, I wanted it cleaned up. I am really happy with the results. They look great now, much higher quality than it was. You may have seen some of these posted to the FB group not too long ago. https://www.zr1.net/forum/attachment...1&d=1711510723 https://www.zr1.net/forum/attachment...1&d=1711510723 https://www.zr1.net/forum/attachment...1&d=1711510723 He also did some blending to improve flow to the valves. Other parts of the package were the coolant bypass for plenum and throttle body, and pinning the secondaries open. The change to the secondaries meant a new tune. All the pieces needed to make it functional again were given back to me, just in case. I rolled around with an AFR gauge rigged up to feed information back to him, but before we could get the new tune dialed in my starter began to die. So the car went back to him for another week and he got the starter replaced. I also bought my own AFR gauge and had him replace the vacuum gauge that was used to monitor the secondary system. I didn't like the idea of a pointless gauge, and the AFR will be useful for tweaking my tune. Which is something I wanted to get into. Timing for all this worked well. This might be news here, but Dempsey is planning to move to Tampa and setup shop there. Probably towards the end of the year. So I was happy to get this big lift from him before he leaves. He has been tremendously helpful since I bought the car. |

The day after getting the car home from Dempsey disaster struck!
My fuel PSI gauge wasn't reading correctly, so I began troubleshooting. Connections to gauge and sensor seemed fine. With the car running, I traced the line out to the sensor. I was jostling the wire loom to see if maybe it had broken somewhere, and looking at the gauge through my windshield to see if anything changed. When I finally got to the sensor I gave it a light wiggle to see if there was something obviously wrong with its connection. https://www.zr1.net/forum/attachment...1&d=1712984959 SNAP! You see, my sensor was hanging off of my fuel rail utilizing a 90 degree sweeping elbow. With almost no force, that elbow cracked off. My, still running, engine turned into a gasoline sprinkler. It. Went. Everywhere. After a moment of shock I rushed around and shut the car off. https://www.zr1.net/forum/attachment...1&d=1712984959 It took so little effort to break that elbow that it was inevitably going to happen. Just a matter of when and where. If I would have hit a pot hole or nasty bump while driving I am sure it would have broken.. and that gasoline would have sprayed into a hot engine bay, and directly onto some very toasty headers. Car #2659 probably would have gone up in flames. I consider myself extremely fortunate here. This was straight off of a cold start. Nothing was hot or up to temp. The car was sitting inside my garage. I got to looking up parts, and quickly ordered some AN4 replacement pieces from Amazon. They show up the next day, get installed, and... now the gauge gets no reading. :-x More digging.. Turns out my gauge needs to ground out on the sensor side. The original setup ground out through the engine itself. The parts I ordered had a handsome black coating that made them non-conductive. Look up raw aluminum parts, can't find exact matches, design a usable set from what is available, order, 2 days, install.. the gauge reads correctly! :) Go to close my hood.. it can't. :censored: My sensor now sticks further out, and contacts the support strut on the underside of the hood. It won't close, can't alter the sensor location with what I have.. god dammit. More looking. Find a place in California that makes a custom raw aluminum female AN4 to female 1/8" NPT adapter. That eliminates a piece out of my setup, and shortens it back to its original overall length. Order, install, gauge works, hood closes, success. https://www.zr1.net/forum/attachment...1&d=1712984959 As an additional boon, the new elbow is FAR chunkier than the last one. It is a hard 90 bend, which wouldn't flow as well as the sweep, but there is no flow here. Just pressure. I am also mildly pleased that the blue fittings are gone. They didn't match anything else. I am now keeping an AN4 cap-end for the fuel rail in my glove box.. just in case. |
Re: 1990 #2659
WOW great job Zach, so lucky you did not go up in flames. Glad it is all sorted out now, well done!

Video from the exhaust competition at the car show last Sunday: 118.1 dB
Another angle recorded by the owner of the car that went after me. I had a lot of people come up afterwards and say they thought something was wrong with the decibel reader, and that I was clearly the loudest. One of the staff running the event echoed that sentiment, too, and said he had never seen so many people flee from the back of a car. Just from audience cheers, I definitely received the most afterwards. Not sweating it, all the fun for me is seeing how people react. I think next time I'll set up a camera on the back recording everyone. I changed my headlights recently to a pair of HWSTAR H6054. These could be wired up in fanciful fashion to allow for blinker functions on the lights themselves, but I like the idea of keeping it simple. I ordered a D-Lumina resistor harness to just make it all plug and play, and that got zip tied behind the light housing. Its a nice difference, and they look better. Installation is super quick, I basically just tagged along on this ChrisFix video. For around $110 total its a pretty significant improvement.
