354 or 392? Hemi? Questions?

According to my info, a stock Chrysler 392 single 4 barrel was rated at 345HP @ 4600 torque 450 @ 2800 with a compression ratio of 10 to 1. Bore 4 in stroke 3.90 in. The middle size early Hemi (354) was rated less and the 331 less yet. Parts are readily available through Hot Heads. There were also Dodge early Hemis - 241, 270, 315 and 325 as well as DeSoto versions - 291, 345. If I had a 67-76 A Body with no engine, I'd definitely have to use my rebuilt 392 in it.
