Holley Lo-Ram Performance I am building a third gen Camaro with an LQ9 in it, with a cam design for 1200-6000 rpm power range, long tube headers, and full dual exhaust. I have a newer version of the Holley Lo-Ram (front feed version of it) because it is low profile and I got it for near nothing. How much power loss if any can I expect with the short runners on it? I am thinking about pulling it back off and using the truck intake I already have.

You will loose power all the way to 6000 rpm with a short runner intake compared to a long runner truck intake . Plenty of videos/ data out there , check out Holdener's stuff on YouTube.

I'm using a stock LQ4 crank with LQ9 pistons and rods, so it can't rev any higher than stock. I have a Comp 54-412-11 cam, 1200 to 6000 power range, stock LQ4 heads. I'll keep working on cleaning up the old LQ4 intake and throttle body, I'll put Holley fuel rails and a set of 36 lb-hr injectors on it. Should work better, I'll save my lo-ram for when I build boosted.
