Swirl is good for torque. That's why "the worst" heads for the Chevy small block are those things with the finger ramp in the intake port.......but guess what? All they came on were trucks and they work great for that. Everything has a place.
The book I am talking about is the Mopar Performance engine book. Not Larry Shepard's small block book, or any other book. The big thick MP book. It's in there where he says it. ........and the testing he was speaking of took place about 1973. Now, what heads was Chrysler making for the small block then?
