Maybe you're missing the first numeral Dean. I found this on Mortec.
Thanks Len, I believe you are correct on the missing number.The block is missing heads and intake but I think it will take a standard type vortex heads and intake.
I wonder what a "ZZ4", roller cam is????
Is it better to use the factory roller cam or change to flat hydraulic and a street & strip cam?
If your block is already setup for a roller cam there's no good reason to install a flat tappet cam... You can use any aftermarket hydr. roller cam and stock style (cheap) hydr. roller lifters. You could also use a solid roller setup but that's more for racing than street....
