All for .370 lift and under ........

Look up the specs on a factory LA 318 flat tappet cam. All are under .400 lift. Now add in the factory poor geometry and subtract another .015-.025. I'll be lucky to have .370 of actual lift.

Is that what you WANT? I honestly believe you're going to cut efficiency, which will reduce mileage too. Try it and see. Who knows?
