Best manifold for procharged sbc? Hey guys, i am about to put a p600b on my motor(the one in my sig). I know I will need to change my cam, but I am curious if i need to run a different intake manifold like the performer rpm air gap. Im kinda new to forced induction so any input will be very helpful.
Thanks-Jeremy

Check out the Holley EFI single-plane. It is a beautiful piece designed by Cutler specifically as a dry EFI manifold:
Available at Summit for $313. All accessories, like fuel rails available as well.
I have it (the Vortec-head style version) on my Vortech-blown 383 and through the 4L80E my SBC made 501rwhp at 7.2# of boost on a Vortech S-trim.
PM me with any questions.

I also have a Holley Keith Dorton - Best offer! Most places sell it for over $900.00 Bob
The Dorton difference--25 more horsepower.
In head-to-head dyno testing, Holley Keith Dorton Signature series intake manifolds outperformed the nearest competition by 25 HP at 7,100 rpm. Engineered by Holley and professional engine builder Keith Dorton, their single plane design yields superior power in the 4,500 rpm to 8,500 rpm range. They fit 23 degree, standard-port Chevy small block heads, have a square bore mounting flange, and are ideal for classes requiring cast iron heads and un-ported manifolds. They're designed for Oval Track and drag racing.
