Best manifold for procharged sbc?
Thanks-Jeremy
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.
