Lee,

How about starting a GB?

Just had a very interesting conversation with an Indy car engine builder who seems to know alot about our engine, and a few people who made the parts!

I need parts #s for bearings if anyone has them.

Thanks

I have been following this with much interest. Since I am soaking up all your info, I thought maybe I could give back some, so I looking up main bearing numbers for you.
Numbers 1, 2, 4 are 10067441 #3 is 10067442 #5 is 10106101
Original manufacturer was Vandervell
My source for this info is the LT5 Engine Parts List
I hope this helps and keep up the good work.

Lee, i hope you find something.
Also screww seal power there are overseas companies that work for pennies like China.

My guy is still working on the bearings overseas.
Between the two of us we should come up with something.

If more joined in the search for ZR-1 parts we would keep the KING going for years.

The guy in this new video series talks about using chrysler bearings on the mains. I think he has done a few motors with these from what my trusty dentist has told me.

I think he talks about it in video two.

George those are the tooling #'s and not the GM #'s. The bearings were made by Vandervell in Scotland, the plant that made them no longer has the tooling. 2 years ago i spoke to the plant manager @ Vandervell & they told me the last time Gm made any LT5 main bearings was in 1995 & after that, the tooling was disposed of.

When we had the bearings made, i had to make a minimum run, the cost for this run was $57,000.00.

Should any of you locate a source to make the bearings, make some oversize, i wish we made some too, but at the time we decided that $57k for some LT5 bearings was enough, they wanted an extra $12,500.00 to make a minimum order .0010 th oversize, if you wanted .0015 th, then another $12,5k and so on.
If this forum and group of guys wish to start manufacturing and sourcing parts, this is a list of items i would suggest you also look into, not only would you sell them, but you would be able to recoup the tooling costs for the limited production.

There is a great need for the following:

• Thermostat housing assemblies
• Coolant crossover pipes
• Cooling hose kits
• Power key switches
• Power key switch bezels 90-95 models are all in great need
• Timing chain tensioners
• Clutch slave cylinder & hose 1990 Model
• A/C Evaporator case, both upper & lower
• Injector driver modules
• LT5 Stamped plug wires (The sales on these alone could pay for the entire tooling of the above items)

Feel free to add to the list of needed parts.

Well, here is my gameplan going forward. I am going to clean up alot of the parts tomorrow, and put them in storage bags. If I am to properly clean up the block, I need to remove the crank.

So once I make sure everything is well labled and put away, and I have some more room, the girdle will come off. Check the bearings, and decide what I am going to do about the crank bearings.

I think everyone would probably want to see this, along with the install.

Let me know your thoughts. Are there things people would want to see better pictures of??? Also let me know it there is anything else that I am going to screw up or cost me out the A$$.

I think when I am done, I am going to put this into a summary of some kind to weed out alot of the mistakes, etc.
