I think it's just the combustion chamber size = different static compression ratio. Should have the same 2.11 intake/1.66 exhaust valves.  I forget what the range is though 6x8 something like 100-120 or something and the 4s are high 80s to low 90s. Although my 4s cc'd at 97ccs so it can vary a little I think.

i looked real close at it and it is a clean engine it is sitting in a 75 safarie wagone that the wrecked so now he selling parts. was great running car with only 72k on and he is the orig owner. so its well worth the buy is the feeling i am getting. i have a 455 out of 73 wagon that i was going to build an play around with but im reading that 400 are much stronger to build...
