The engine with the heads off is either a 331 or 354 truck or industrial engine. You can tell from the pistons. Those are low compression, 7.5:1. That denotes the truck/industrial thing. It is also at least a 1954, as all the 53 and back had the extended bellhousing. That has the short (more desirable) conventional bellhousing. Same bolt pattern as the LA small block, but still requires an adapter plate, because the dowel pins are in different locations. That's probably a pretty good score. Where are the heads? Make sure to look at the exhaust ports. If they are large and oval, they are quite good. If they are round, they are the earlier ones and have been swapped out. Round exhaust ports suck on early Hemis. Look on the block directly behind the timing cover on the top of the block. There's a pad with some stamped numbers. Get those and it will tell you exactly what it is.
