Re: Secondchance - 380 build begins!
We have a few good porting guys out there for sure. Ryan's work is just on a different level.

The floodgates are open..........when one Wazoo starts...............this is going to be fun.
Can't wait to get together and share notes. |
Re: Secondchance - 380 build begins!
Nice deal Rich!!!!
Another potential high hp wazoo car coming :cheers: David |
Re: Secondchance - 380 build begins!
Last post was in August 2013. Now an update, finally my motor is out of the car, plenum and IHs are with Lee. I will be picking up my disassembled motor from Frank who was tasked with removal and disassembly. Next will be cleaning the block and taking the pieces to a machine shop for valve job and partial assembly.
It has been a long wait (to find right guy to do the dirty work since I live in a condo) but finally I am beginning to see the light! http://i658.photobucket.com/albums/u...psb6830f5b.jpg http://i658.photobucket.com/albums/u...ps923f5593.jpg |

"you suck! I have 380 envy!!! :cheers: cant wait till you are both done to check them out". Rickey, It's been a long winter. Never thought I would get to come this far. Without the WAZOO gang, never would have made it. |
Re: Secondchance - 380 build begins!
I hear ya brother Yun, one couldn't ask for a better bunch of guys. I also hope one day to have my LT5 massaged and will reach out the WAZOO collective for assistance. We gotta get our good ole farmer brother Darrin to break off a piece of land for us and build a track for tune & testing. :-D

Re: Secondchance - 380 build begins!
Thanks, Lee! Can't wait to mate those IHs and the plenum, finished in Tiger Drylac anodized silver, back on the heads!
Disassembled motor was dropped off at the machine shop today. Of course, I was totally lost until Phil showed up and started talking to the shop owner. Lloyd, the owner of the machine shop, obviously was a total gearhead and I could tell how much he was enjoying talking to Phil. Also got a tour of the shop. Phil and Lloyd did some forensics on how I ended up blowing exhaust into the cooling system. If I understood correct, it was a combination of mileage and a defect on the head gasket. Mind you, both head gaskets were intact - no distortion. Below is the 1-3-5-7 head. Problem was with the #5 cylinder. http://i658.photobucket.com/albums/u...ps62de0208.jpg Cylinder #5 - notice the notch? http://i658.photobucket.com/albums/u...ps980d00c5.jpg Corresponding segment of the head gasket. http://i658.photobucket.com/albums/u...psc68173f9.jpg Interestingly we found a "v" shaped depression on the other head. It turns out head gasket had a small imperfection, which was quite visible, responsible for this depression. Perhaps, there was some over-heating due to low coolant when the OEM radiator went that exacerbated this weakness. Whatever caused the sequence of event, this LT5 served me and served me well for the last 13 years and 140,000 miles. Better yet, I get to have a hand assembled 4" by 3.75" 377!!! - I LOVE IT!!! I have always loved cars and especially Vettes. Owned Vettes since 1979. However, had I not run into the Net Registry and WAZOO in particular, I wouldn't have known of what can be done and couldn't have even dreamt of 380 build. Thank you Net Registry and WAZOO!:cheers: |

My engine has the following additional mods. -37.5 mm inlet ports -Headers -2.75 Inch PowerEffects exhaust System -catalytic converters -SGC base chip (thank you Aaron) With 800 miles on the clock and without a final adjusted chip I went on a dyno and it pulled about 560 HP at the crank. Here in Europe we measure always the power at the crank, unfortunately. The car has stock gears and is as fast as a C6 Z06. The weight of my ZR-1 is 3'530 lbs With a adjusted chip and better modified secondaries there is still space for some additional HP's Sam |
Re: Secondchance - 380 build begins!
Well Yun, the mystery is solved. Great write up on the head gasket, sorry I missed you guys at the shop. No more stock radiators for your...Huh? Keep the write ups coming....I'm right behind you.

Re: Secondchance - 380 build begins!
I had the Pete Intake cam w stock exhaust combo on my 5.7L. Very nice and smooth. After going w the exhaust cam it made things a bit more raucous but added another ~ 20rwhp. BTW, I did the calibration for my config as well as GC's 380.

The engine has a 12.5 : 1 compression ratio and run with stock head gaskets. As mentionned it has catalytic converters installed. You can feel the acceleration difference if it run with or without cats. Sam |
Re: Secondchance - 380 build begins!
Here a Youtube Video of a friend of mine who run his 350 cui Callaway LT5 at night on a german Highway.
https://www.youtube.com/watch?v=VaB0...ature=youtu.be 316 km/h is like 198 mph and the car was not at its speed limit. I love the german highways because there our biests can show what they really can. Sam |
Re: Secondchance - 380 build begins!
Updates:
Engine bay cleaned in preparation to received updated motor - 2 cans of Gunk, Dawn and water scrubbing followed by Deep Purple degreaser. http://i658.photobucket.com/albums/u...ps0c0fa0ae.jpg Cleaned up block with new 4" liners. Notice the torque plate? http://i658.photobucket.com/albums/u...ps0fa4931b.jpg Cleaned up lower block. Notice discoloration on main bearings? Lloyd told me this rebuild was timely. http://i658.photobucket.com/albums/u...ps8299409c.jpg Close up of bearing surface. http://i658.photobucket.com/albums/u...ps5ec63ff0.jpg |

I'm curious if any more HP comes with this PE 3" hardware, over what Marc says is available by opening up the resonator restriction (I think he says 10??? ), Jeff? [Shrek]? You happen to know? I'm sure I lost double-digit HP's + TQ with the automatic - tranny fluid pump, TQ convertor, etc., ... |
Re: Secondchance - 380 build begins!
Would you mind taking a shot of the #4 & #5 main bearings? The #4 seems to be the one that wears the most. I think the wear & wear pattern look very good. How many miles on the engine?
Thanks for the photos. |

If I can stop by the shop early next week, I will take close ups of all. I have 140,000+ on this engine. May I ask what prompted "the wear & wear pattern look very good"? |
Re: Secondchance - 380 build begins!
Yun,
I'm with Jerry, by the looks of the photos the bearings appear to be in darn good shape for 140k miles. |

Re: Secondchance - 380 build begins!
Awesome stuff keep the updates coming !! Love watching motors get built :) Unfortunately for me I built a 388 for my 93 and it blew up, and shelled out for a all out 370ci build the second time around.. and then bought a z :-x I sure wish I spent all that on an LT5 build ! But as my wife always says I'm OCD when it comes to anything that I want... and a built LT5 is what I want!! :dancing
Picking up a lot of info on build ups from threads like yours thanks again for sharing :) If I may ask all the guys, Is there a source atm for stroker cranks ? OP did you consider a stroker crank? |

Stopped by the machine shop this afternoon. Short block is almost done. Lloyd was torqueing the rod bearings - I think! http://i658.photobucket.com/albums/u...ps91c6e89a.jpg A peek from below. http://i658.photobucket.com/albums/u...ps98859b0a.jpg A close up. http://i658.photobucket.com/albums/u...psbf746c68.jpg |
Re: Secondchance - 380 build begins!
