I got a Chevy 350 wit a small cam other little minor performance parts and I was wondering if I changed from stock intake will it add horespower? I dont want a hot rod but want to be able to move it easily. Will some hooker headers add horespower also?
An Edelbrock intake alone may add a couple horses, but not enough to be really noticeable over stock. It really depends on your application. For a lowrider, you're going to want a dual plane manifold that is designed to make more torque from idle and up, since you're trying to tug a lot of weight, and you're not doing any high-RPM racing. When used in conjunction with a properly-tuned carb and your cam, you should have gained some power over stock for sure.
The headers should be much less restrictive than the factory exhaust manifolds, so regardless of whether you change your intake or not, you will recognize a few extra horses, and possibly another MPG or two (depending on your carb and cam setup) due to the increased air flow.
Let me know if I can help with specifics (like picking the right intake/carb, are you even changing the carb?), but that's just some real general info for ya.
if you get an intake manifold it would be best tio get a spacer also dependin on the size of carb/intake setup you gonna run. i have a weiand dual plane intake and a 650 carb so i went w/ a one inch spacer.
