Early model roller cam in a later model motor?
 
Hey everyone, I am going to trying to put a roller Crane cam out of a 1985 LT1 350 Chevy into a 1993 ZZ3 roller motor. I have been told that Crane cam part #119641 will not use the cam plate to hold it back and that I would need to use a pre 1988 cam gear and a Cam button.
Any thoughts will help.

Thanks Ricksgtx

I'm pretty sure that lt1 parts can only be used in lt1 engines, they are not interchangeable.

Yes, you can put an "old style" roller cam in a factory roller block by using a cam button just like you would in a pre-roller and then you can use the factory roller lifters but there was no LT-1 in '85. The early style LT-1 was '70-'72 only and there are those that would argue that '71-'72 don't really count because of the lower compression.

Is this a gen 1 lt1 or the gen 2 with the tpi system?

Bigdog, This is a Crate ZZ3 motor 350 aluminum head (58cc)that came with roller cam and a duel plane intake set up with a 650 holly double pumper.

Thanks

Hippie, you are correct (as usual) no LT1 in 85 but what about the cam timing gear? do I need to get a older model cam gear along with the cam button?

Flattery will get you everywhere. I only wish I was correct as often as I think I am. :rolleyes:

Yes, you will need the early style timing set.
