Post some casting numbers to know what it came out of. I'm not sure if ALL (but many) high perf pass blocks were 4 bolt mains. At least mine is for that matter. :cheers:

"Hi Perf Pass" isn't all that rare and doesn't mean it's a 4 bolt main block. My motor is also stamped "Hi Perf Pass" and it's a 2 bolt block. Were you able to find a casting number on the heads yet?

I have not pulled anythingthing apart yet. I will wait till i get a complete gasket set. I found a nice 81 Z28, no motor or trans. I bought it today.
Instead of fooling with the vette and getting side tracked AGAIN, I will build a nice street car with this. :seeya
