WTB 93-95 Piston Assembly - ZR-1 Net Registry Forums

billybaloneey · 10-22-2009

I would like to buy two (2) usable and complete piston assemblies - piston, piston pin, rings (all 3 of them), and connecting rod, from a 93-95 LT5 engine. If you only have part of what I need, let me know.

Thanks,

I have these from a 90-91 motor I don't know if they are different or not I thought the pistons were the same??

If they are the same and you need these let me know $100 each comes with piston rod and the rings still on them.

I recently bought a set (8) of used pistons/rings/pins/rods/liners off of eBay...out of a '90 LT5. I was in Chicago last Monday and stopped by Marc H.'s place to visit. He informed me that there is a weight difference between the 90-92 and 93-95 piston/rod assemblies.

Also on the "Members Only" portion of the ZR1netregistry...the section about "LT5 Engine Specs" it does mention differences....the rods were lighten, pistons were strengthened, differences in all 3 rings, it even says the piston pin had a design revision. Physical dimensions are the same.

So I now have a near complete set of LT5 piston assemblies...but, according to Marc...they are just a little different in weight for my '94 rebuild/project engine.

You were actually one of the few I thought might respond with what I needed...but apparently the earlies are not 100% interchangeable with the laters.

Thanks,
