As stated I have 2 57 Chevy 265 engines . One is a bare block ,$200. The second is a Short Block housing a Reciprocating assembly with 12:1 pop up pistons , no cam . $550.These are kind of unique for 57 as the 283 was more prevalent . Interestingly these engines were available in some 57 cars and in the trucks . They were painted Chartreuse ...greenish yellow as opposed to Chevy Red or Orange . I also have a set of used 57 Chevy 283 FI /Power Pack Heads casting 3731539 with Corvette finned valve covers, $600. I can bring all to Spring Carlisle this week if you PM me with interest . Space R48 or under covered car corral with 55 Chevy Gasser. Greg.
