I have a 92' Chevy. I am looking at swapping a ZZ4 shortblock, LT4 Hot Cam, GM Fastburn heads, and a Edelbrock Pro Flow FI kit into it. Will a LT4 Cam go into this block. I don't know if they have a distributor gear drive on the back of the cam or not. I will need to upgrade the Edelbrock system though with bigger injectors.
