For sure........ it’s knowing just how big is big enough without being too big😬



That is why I recommended what I did. The intake is done at 5000. I don't mean its past peak, I mean done. To maximize usable power, probably a cam that peaks at 4500 to 4600 rpm.

Change the intake, totally different game.
