I've seen A LOT of posts about making HP with a 318-So why is it so ???

8 to 1 to 9:1 makes more difference than 9:1 to 10:1
cam needs to match the compression or dynamic compression for .006 seatduration
but 60 over 318 vs 20 over 360
how much difference does the .050 larger bore make on a street motor?.090 or .100 for a 340?
now Magnum blocks seem to be better materiel and easier to get 9.2:1
so if the 318 needs pistons vs a stock 360 magnum no machine work requied for me it's no contest
