I think the Wallace Calculators has a header sizing program on it.

I'm using a 2" header with a 4" collector on my small block. When I ran the program it came out real close to what I already have on there. I think you'd be better off with a larger tube.



-Header tube or collector???



Tube size. Is this going in a B body? I think Hooker makes a super competition 2 1/8 primary tube size with a 4" slip fit collector.
