Thread: Headers for 69 chevelle?

Tweet

I'm going with the doorman manifolds, 647-501, $111.99 Ea. @ O'Reillys. I have flanges around here somewhere, I'll see if they fit or else I'll have to order some. Or they might come with. That would be nice.

I'll let y'all know how they fit.

OK, I got on doorman's site, and cross referenced the part to a 1990 Chevrolet C60, so maybe that will give the kid at O'Reillys something to go on. Also I found doorman's flange, but not the shoulder (pipe).

I'm thinking to cut a wedge out of the manifold and weld it back together. (MIG). Is this feasible since the manifold is cast iron, would it crack apart in use?

Mike, I looked at those, and they are about a quarter inch longer, and would exacerbate my clearance problem.

These manifolds are not corvette specific, but visually, they are identical: I hoped they might work better, as I'm working on a chevelle.

Maybe I'll return the manifold that I didn't weld shut the holes, and modify the bloody header.
