: Intake manifold

05-06-09, 10:39 AM
So on the built 350 I put in the 90, I have an edelbrock spreadbore intake manifold with an adapter to run the throttle body injection on top. I was able to get a TBI intake manifold and was wondering which one would be the better setup. Someone told me that the TBI injection doesnt have enough flow to work good with the edelbrock. Just wondering which combo would work better. I have an RV cam and dual exhaust.

I'm not crazy about the adapter idea because you're using the manifold in a way that it wasn't designed for. I think Edelbrock makes a TBI intake which should be better than stock. I would still go with any TBI intake over the spread bore Performer.

It sure would be easy to put a Quadrajet and a one wire distributer on there for some trouble free driving.

EDELBROCK does make a tbi manifold. I beleiev it has the same specs as the OEM manifold. One option for the tbi is to bore out the actual tbi units.

So I put the TBI intake on and a big inprovement. lots better torque.
