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

I don't know..figures are all over the place.Yes stock early 340's were 9.5:1 give or take.But i know of 2 rebuilt to stock spec 340's that dynode 276 and 281at 5200 rpm.I also know of a stock spec. rebuilt 426 hemi that dynode 465 At 6200 rpm. But a stock headed 318 at 8:1 with a cam and intake surpassing a stock 340?
I'd take the magazine numbers with a grain of salt.
