Intake manifold question

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.

Re: Intake manifold question

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.

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 crazyL

Re: Intake manifold question

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.
