Question Mid-Length Small Block Headers

Anyone know of any Mid-length small-block headers that have primaries larger than 1 5/8?

Just got a '72 Malibu I want to build up as a daily-driver and was thinking about a mild 406 small block. I don't want to live with long-tube headers but haven't found anything for a small block with bigger primaries than 1 5/8" and also will give me the ground clearance I need for the speed bumps I regularly deal with.

Thanks!

For a mild daily driver you probably don't need anything bigger than 1 and 5/8

Re: Mid-Length Small Block Headers

I searched various vendors/header manufacturers (including summit/ speedway motors) and didn't come up with any mid-length headers for a small block Chevy in a '72 Chevelle with larger-than 1 5/8" primaries.

I notice most all of the crate small block 400-427 crate engines recommend 1 3/4" primaries.

I won't sweat it. I'll stick with 1 5/8" and if I loose a little peak power so be it. Thanks all!

Re: Mid-Length Small Block Headers

If your not going to use long tubes, you might as well stick with common manifolds.

You're just jealous because you can't hear the voices!
