1990 crate motor

Hey guys,
I've started looking for a crate motor for my 1990 vette. I started looking at summit racing with no luck. :banghead: They said that they "skipped" over the 90's L98???? However, he did say that they had ZZ4 motors in stock.

What is the difference.....?

What I would like to do to the car:
1. replace engine with exact duplicate
2. replace engine harness and cosmetics
3. replace exhaust system

What is everyone's opinion on the replacement motor and where else should I look for a great deal on a crate motor???

Thanks,
 
Let us know....we have several options & a few already done that will fit in. We can also do the swap so it is all done right.:thumbsup:
 
yea ditch that l98 and go ahead with an LSx if its not too much work. hell even an LT1 would be a great improvement
 
An LSx is a huge ordeal for a C4. Even the LT-1 is difficult because of the Digi-dash.

I've heard of some issues with GMperformance blocks. I'd talk to a local shop like revxtreme first.
 
Well, after searching for different intake manifolds....I've decided on the ZZ4 crate engine.

I know 4 things:
1. I could use the old intake from the L98
2. I will need to acquire a new prom chip for the computer
3. swap my oem 6 3/4 inch balancer
4. swap water pump

Questions:
1. Do I want to use the old intake??
2. does the balancer come with the ZZ4 crate motor??
3. any ideas where to look for a new prom chip??
4. what headers should I install??

Thanks for everyone's input,
Jered
