Cylinder Head Choice

You wanna do a 10.5 in the 1/4 mile?

It’s a tall order for a 318. It can be done. You’ll probably hate driving it on the street. I’m going to say something I don’t say much, but here it is....

You “might” wanna start with a bigger engine.
(And a camshaft nearly twice the size. Add 50*’s of duration to start with.)
