I'm listing for a friend. the block is a 68 396/375 camaro but the rest of the engine is 66 396 /425 Corvette. Closed chamber snowflake heads, pre-emissions cast exhaust manifolds , internals are 425 horse vette. Block has not been decked the numbers are still on deck surface correct aluminum intake etc. Complete pan to carb. Located in Pittsburgh Pa. Might be a case of the parts being worth more separated but not my call. contact Paul 412 414-6419. Out of a really nice 66 roadster which is also for sale.
