351vs400 I just figure with the same top end the smaller cubes it's got to be fed better. Same as a 302 is ok but the 351W is a pig cause it uses the same head/valves.
50 cubes in that case is a detriment not a bonus.
A point in compression is obviously nothing to sneeze at either, but there are more factors in the 351's favour than the 400's.
The 460 is just cool regardless
