Which Intake To Use?????

[slider]

I am looking at replacing my performer intake manifold. It has a crack in it. I have a 350 that is stout, World Products Sportsman 2 heads, 268 comp cam, true roller rockers. Jet stage two Q JET, headers, 456 gears turbo 350 trans, etc. I have been looking at the performer rpm manifold or another performer manifold. I am currently running a blocked cross over so the carb gets no heat MAN THAT SUCKS WHEN ITS COLD. Anyone out there run the Performer Spreadbore rpm manifold? I see where its a little taller and they say it will help a modded motor breath better. I hate too loose too much bottom end. Thanks for the help, Slider

I've used Dart Kool Can

and World Products Dart 2 Sportsman intake

Both are very good intake manifolds. The Dart "Kool Can" is a air-gap.

i'd go w/ rpm or air gap.from what i've heard you dont really lose much bottom end going from performer to rpm

There's always adaptors.

I'm running the Performer Airgap on my 383. It runs great down here in Florida but you might have problems with your cold winters up there. I've run the regular Performer on a lot of my engines and it works great. You'll also have the heat runner to warm the bottom of the intake in the winter.

im running a power+plus crosswind manifold, you do lose some lowend power but i would say its great value for money and it really does improve higher rpms. i didnt get a polished one and the quality of machine work wasnt the greatest so i would recommend a polished one.

at least a Performer RPM Air Gap or better. the Performer has no business being anywhere near the rest of that engine.
