OK. Both the 351M & 400M use the same size 2bbl (1.686/1.21 ) the same heads with the same valves. The 351 has a little over 8 1/2:1 compression & the 400M a little under 9 1/4:1. Yeah the cams are different but with what cam grinders can do these days, I think that's pretty much a wash. (probably wrong).
The 75 & 74 460"s The valves, cams are the same the compression's are similar But as Billy reminded us:
