302 sbc.... lightweight high revving. big power............dual quads. runs strong all day

ZZ572 should make things interesting.:nod:

So Johnjzjz, without disrespecting you or discounting what you experienced 30 years ago, I still feel very comfortable saying that COPO cars were 427 cubic inche engines swapped in at the factory. That is not to say you did not stumble across a non-original example or possibly some sort of factory "mule", but to make the blanket statement that COPO cars were not 427's would be erroneous in my opinion.


you know i should not have just gone on what i recalled with out looking it up --- in the seventy's we did many many BBC and in those days unlike today no information was available no computers only paper books at Chevy and a cross to a motor # i was at this writing sure i had a book in my collection that confirmed what i had wrote and i might still find, but after an hour of looking i have not sooo not making any excuses, it would seem i was incorrect, but if i should find what i am sure i have read in our library as well we keep in the shop i will post it up, sorry for the mistake -- jz

I would pick a 502 to throw in my Cutlass.
