360 sb on dyno

That engine would be not so hard to get there with something as small as a xs282s camshaft.

Or 570hp pushing a 3100# car to 121 mph. Nope.

I have seen engines leave shops and the owners try to feed 500+ hp with a 5/16 line and stock fuel pump. No kidding it runs badly and dies at 4500 in 2nd gear.
