I believe 5.85" Eagle rods and 4" Diamond pistons. Flying Ryan and Rick Watters of Rick Watter's Racing Engine ordered pistons and rods. I don't know enough to select and match pistons, rods, rings etc...
Rick Watter's also handled crankshaft regrind with their choice of machine shop.

Re: Secondchance - 380 build begins!
 

Looks like with the 2.000" rod journals he didn't have to notch the block to clear the rod bolts like I had to.

Re: Secondchance - 380 build begins!
 

I have to put my foot down. That's PORN on our forum.

Please take it down immediately and email it directly to me!!!!

Lloyd commented that all fit real good and he liked the choice of parts. He said the mains were sticking at first so he had to work the main bearings a bit.

David,

Thanks for the compliment.

Re: Secondchance - 380 build begins!
 

That's what has me really worried with my build, this is the second build that I have seen that have encountered this issue.

Re: Secondchance - 380 build begins!
 

I am clueless how sticking mains can be fixed. I can ask and find out.

Although I don't know enough to assemble the motor, it's a real treat to be able to stop by, take pics and see it being assembled.

Re: Secondchance - 380 build begins!
 

The aluminum block and girdle move around a bit. This just happens on the LT5. Kind of scary the first time around. Every bolt needs to be torqued on the whole bottom end before turning the crank.

Nice part of the 380's (3.750 stroke) no block work needed, even with the big 2.100 stock rods:-D

Re: Secondchance - 380 build begins!
 

Good to know, I was thinking you shouldn't need to torque all the griddle skirt bolts.....Thanks for the great tip!!
Rich

Re: Secondchance - 380 build begins!
 

I took my block back twice.....every time I torqued it the crank would stick like an SOB......6K miles later no issues. A lot of it is the engine flexing on the stand....no worries!!!

No PORN for you! Come back three years (Soup Nazi)

Re: Secondchance - 380 build begins!
 

There is a slight difference in the fabrication of the King thrust bearing, compared to the OEM thrust bearing. The OEM thrust bearing flanges are spot/tack welded to the bearing shell and does not have any fillet on the back side. The King thrust bearing is formed from one piece and has a very small fillet which interferes with the bearing surface in the block (both upper & lower crankcases), resulting in the bearing not being completely seated. The result is a tight bearing that doesn't allow the crank to turn freely. The solution is to simply grind a slight chamfer (abt 1/32") on the outside edges of the bearing surface if the block so that the bearing shell will fit completely into the main bores.

When we ship a set of King Main Bearing to a customer, a detailed instruction sheet is included which describes the modification required.

Personally, I think the King Main Thrust Bearing is better than the OEM. I have seen a few of the OEM bearing that the thrust flange welds have cracked/broken.

FWIW, we also had King make +0.0005" main bearings in addition to the std size, so the main clearance could be in the middle instead of the top of the recommended clearance when building a new engine.

Re: Secondchance - 380 build begins!
 

Original cam cover emblems touched up. These seem to have strange finish - almost like black chrome. I thought about replacing with Lee's replica but decided to touch up and reuse.

Re: Secondchance - 380 build begins!
 

I will run over and make sure there are no flaws, then I should be ready to ship very soon

Re: Secondchance - 380 build begins!
 

Looks great! Thanks Lee.
Heads are ported awaiting valve job.

Re: Secondchance - 380 build begins!
 

I am going to get everthing packed up, the airhorn had a gassing issue so we are redoing it...had some pitting due to gases trying to escape the aluminum. Everything else turned out awesome, will have everything packed and over to Fedex in the next few days.

Will ship the airhorn once its redone

Re: Secondchance - 380 build begins!
 

Ported heads:

Re: Secondchance - 380 build begins!
 

Maybe u know this already, but if that "pad" for the ignition module wasn't masked off before PC, you'll need to remove the PC before mounting the module. Can't tell from pic.

Re: Secondchance - 380 build begins!
 

I would guess the "sub-contractor" had that under control?

Re: Secondchance - 380 build begins!
 

If not, will figure something out.

Re: Secondchance - 380 build begins!
 

Clean your shoes.

Re: Secondchance - 380 build begins!
 

Tough to do that while assigned to a construction site.

Re: Secondchance - 380 build begins!
 

Yun, Your car was fun to drive when she was stock, I cant imagine how much fun it will be when she is a "380"

Re: Secondchance - 380 build begins!
 

Coming from you, with great Zs, that's a hell of a compliment.
What started as refurbishing of tired parts after 100,000 plus miles went out of control and I love it!:cheers:

Re: Secondchance - 380 build begins!
 

Engine reassembly was postponed due to unforeseen damage to cam chain idler assembly.
Spent this afternoon painting letters on the cam covers.
Last time I did this was 5 years ago and at that time I painted letters while the cam cover was on the car. This time, with the cam covers off the engine, should have been easier but not the case. Hand was not as steady and couldn't see as well as I use to...

Re: Secondchance - 380 build begins!
 

Looks great Yun!

Re: Secondchance - 380 build begins!
 

Having tried free hand I decided to use masking tape and spray for the plenum. Rather spend time cutting the letters with Exacto knife then go through the stress of keeping my hand steady.

Thanks Lee! I am very happy with my choice of color and satin finish.

Somehow picture looks bluish but in realty it's satin silver finish.

Re: Secondchance - 380 build begins!
 

Looks great Yun,what type paint did you use?

Sorry i missed your call, i was attending seminars when you called. Hopefully next year you will come. Gunny was a great host and a hell of a driver. He lead the group and i covered up the rear in the Mountain Run,

Re: Secondchance - 380 build begins!
 

I just called to see how much fun you were having.
As for the cam cover, IH and plenum, I opted for powder coating as opposed to paint. I am of belief that higher level of finish can be had with paint but powder coating are more durable - just my opinion. With my insistence in driving my Z all the time (as long as it's not raining) durability of finish was my priority.
See you soon!

Re: Secondchance - 380 build begins!
 

Intake plenum with lettering.

Re: Secondchance - 380 build begins!
 

Thanks You,
Did you also power coat the emblems on the cam cover?
Thanks,
Nelson

Re: Secondchance - 380 build begins!
 

Finished plenum looks great !! I really like the color.

Re: Secondchance - 380 build begins!
 

Hi Yun. Plenum looks amazing. Congrats on making your car better than new at a 100k+. I miss WAZOO and all you guys.

THey should be on the wall - not the motor http://www.zr1.net/forum/images/icons/icon14.gif

Emblems are factory original. Just touched up w/ paint.

Thanks guys for the compliment!

Hello ZR-1 gang

I have a question to all whos engines run with steel sleeves. How much oil does your engines comsume?


Sam

Re: Secondchance - 380 build begins!
 

We got together and I helped Phil and Jim install camshafts and cam chains.

Cam chains being installed after cam guides and idler.

Jim and Phil busy over camshafts.

Camshafts and chains in place.

Tomorrow we are going to time the camshafts w/ degree wheel.

Re: Secondchance - 380 build begins!
 

Hi Sam,

I don't know yet. I expect oil consumption to be reduced due to the fact that my LT5 had 140,000 miles.
FYI, L.A. sleeves are cast iron. I understand the factory nikasil liners retain oil on the surface better then cast iron liners but after 140,000 miles, new sleeves and the whole engine being refreshed should reduce oil consumption.

Re: Secondchance - 380 build begins!
 

I did Pete's intake and exhaust cams. Glad I did!
