I was just about to refer @'63GT to Richard Holdener's videos. I was quite surprised to see the dyno graph overlay of boosted vs. no boosted. The curves are damn near identical, just higher on the graph (more Tq and HP). Therefore, your expertise in NA head porting isn't null and void for boosted applications. FYI. As much as I try to not be the "bottom of the page" cam selector, I always tend to lean that way.... I like your style..lol. thanks for the education on the RPM range. Didn't know the LSA was a limiting factor on that.
