Intake manifold question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

cwolfe · 09-07-2012, 11:12 PM

Hey all, I'm putting a crate 350 in my 65 c10, and I have a question. I planned on pulling the intake from an old 350 and using it. I took it off, cleaned it up, and out of curiosity, put it on a piece of granite that I believe is flat, to see if it was flat. The part that connects to the head looks like it has a slight curve. The ends are touching, but I see a little light under the middle. Is that normal, or do I need to get it machined, or is it no good. Thanks for your help.

No that is not correct. The machined surfaces should be straight and flat.. Before you spend very much on machining those surfaces flat, compare that cost with what another good used one or a new one costs.

Maybe an edelbrock 2101 or a 2701.

Ditto! maybe the stone is not flat? You might pop the valve covers, & set the intake on the engine(no gaskets), & use some feelers to find the story

I'd get an alum. intake regardless.

I wouldnt use that factory cast iron boat anchor either way. You can get a used edelbrock alum intake for probably 50-75 bucks. It will perform a ton better than the factory piece ever did.

C,mon guys....it has got to be good for a door stop, or a wheel chock....& yes , probably heavy enough for a boat anchor
