Didn't say there wasn't cfm left in them, but just because they flow more don't mean they will make more power.Carnut1 wrote:Lots more avalable if you work for it with bowties. Chart off Stan's website. Thanks, Charlie
And, this is a pulling truck engine. They are kinda endurance engines. They also need a very wide power curve if you have it set up with enough traction to pull the engine back at the end of the pull.
And my time would likely be better spent on a newer set of heads. Probably come out power ahead in the long run.
If he ends up just throwin a 3.75 crank in it I'll go over the heads over the winter.
Right now this head is legal in Pro street http://www.compcams.com/Technical/Catal ... PDF/16.pdf
That head on a 412 cube could make enough power to make a small block competitive in Pro street.
Kinda depends on what one is willing to spend to run up front, vs less money to run mid pack or even less to just hook to the sled.
