Would a Trans Am intake benefit this truck at all - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Syco67 · 07-10-2004, 02:09 AM

My friend offered me a factory 4bbl aluminum intake that came off of his 83 Trans Am with a 305. Would it be worth my while to put it on a 69 GMC 3/4 ton with a 350. It is currently a factory 4bbl truck but I figured the aluminum would reduce some weight, and maybe, just maybe the TA manifold flows better?

I don't know much about chevy's, I tend to work on a lot of different things, so any help is appreciated.

There a good intake for a stock alum.

Ive got a couple one of the local machinsist says there as good as a performer edelbrock he says its a similar intake but there cross drilled between the planes.

you will have to make an egr blockoff plate of have an egr valve thats the only down side to them.

They arent that good, but better than the mid seventies cast iron intakes. They are a low rise intake to fit under the low hoods of the F bodies. Find a good used Performer RPM or similar intake, much better to begin with. If the 305 intake is free, then I guess you wont be out much except gasket costs, might be worth trying out.

a 20+ yearold smog manifold?? even for free i wouldn't spend the time or money on gaskets to install it

I would look around a bit, you should be able to score a good used Performer for around $30-40. the Ta intake will work, but I doubt that you will see much improvement over the stocker. crazyL

I would not even bother, it will have provisions for EGR, and a host of smog attatchments that you quite frankly do not need. I would do as suggested and find a Performer manifold made for your year of truck. (with no smog)

That intake is about equivalent to a normal Performer. Other then having the EGR passages its not too bad.

Its lower profile than a performer but not much. Its designed for emmissions so it will be a little more restrictive than a performer and especially a Performer RPM. The Performer RPM was designed similar to the old 70-72 Z28 intake, high rise dual plane for good low end power with better top end power than the low rise.
