Nice big difference what compressing ratio did buddy of mine just put together a 424 SB with 10.50 C/R with a big cam told him good luck it will be a dog.
my 416 is 10:1 with a 272@.050 .658 lift at the valve solid roller. Runs on 91 octane and has been 10.54 in a 3550lb street car. But I agree more compression is usually always better.
