Well steve thanks for asking but I'll tell you this much, I sold a real nice 1963 Split window Corvette an original survivor 327 300 hp 4 gear car from Cailfornia and with the $$$$$ I bought the 052 ZL1 engine and a 69 Camaro shell also rust free car. To better answer your question I know of a ZL1 engine for sale for $25 k. not quite like my 052 engine but I guess when empty blocks sell for $12 k you should have $18 to $25 ready cash. Just my 2 cents
