Found a LT5 at the junk yard with fire damage - Page 2 - ZR-1 Net Registry Forums

Maybe they refined their process in the later years? IIRC, 93 had the 4 bolt mains, maybe other changes to production were also made.

Side question, 2 bolt vs 4 bolt, does it really matter on the LT5? And is there any sort of advantage of having a 2 bolt main machined to four bolt? Not that I have the means to have to have it done, just curious.

I believe that Marc Haibeck said that 2 or 4 bolt mains do not really make a difference. He does his 510 HP package on both types of engines with no durability issues. --Bob

Appreciate the knowledge!

Motor is still being cleaned. I'll have to take some picture this week.

If you go, I have a small parts request if you can. I need the coolant hose/metal to ND FROM the firewall outlets to the thermostat assembly If you can get the thermostats housing quickly I want that too. Be sure to take and wear and hardhat.
