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

Heck, I made ifrc, 286hp and 265 tq to the rear wheels with a 318 in the car to the left without even trying...XE268H, Indy closed chamber LA-X heads, 10.3:1 comp and pistons .012 in the hole.
Edit: I found the dyno sheet...power at rear wheels remember...
