MM&FF/Livernois finds 430hp NA with FRPP, engine dyno

Looks like a ported heads, cams, frpp intake manifold got to 430 on the engine dyno. About 365hp to the wheels with 15% drivetrain loss? Seems some folks have got more than that with stock manifold? Sorry if repost but my issue just came in the mail and this jumped out at me.

Wouldnt a chassis dyno be showing rwhp? Or am I mistaken?

oops, corrected. I meant engine dyno...

Is this on a manual car?

I saw that build too, that may be the way I want to go. Plenty of power for the street probably enough for low 12's? If I build though I want to build one with a little more compression(11:1) which would probably provide a pretty good boost in power. I wanted some input of if anyone think cams with more lift would make that much difference? I am a big fan of NA and I would love to hear the 4.6 scream at 7500+.
Big question is what crank would be best? Can you get a stock crank balanced to turn that high?

The test was done on an engine dyno, not chassis as the title says.
