    hi everyone I was wondering if an aluminum single plane intake manifold would really kill my low end torque. A relative is giving me one for free tomorrow and i was wondering if it would be better than the stock one. I am currently rebuilding my motor so this would be a good time for an intake swap. Would this one be any better than the stock one? I have a 350 that is stock except for a set of headers. Thanks for the help!

    Single plane intakes are more beneficial for higher RPM use, but some can be used. It depends on which intake you have, get the manufacturer and model and do some research before using it, some are made for a multi-purpose type RPM range which would be usable for you, and others are race only pieces which you will be sorry you put on your engine. A dual plane high rise type would be a better choice, maybe you can trade/sell it to a bracket racer and get the one your looking for.

    Get the intake number.

    If you have the classic GM "equalized" dual plane intake then it won't hurt to put it on there. Drilling the hole between them was one of GM's dumbest things.

    the only decent 1 plane i have ever used was a Torker II. decent low end, breathed reall good up high.

    I would get a Performer RPM with Air gap and a 1/2" or 1" wood spacer (a little testing might help find out whick is better for your application). the cooler temp will help make a bit more power, the spacer will give you a bit more top power, but still the benifits of a dual plane

    Ok I just got it today. It's a Holley Street Dominator, rated for 2500-8500rpm. Is this too high?
