Sbc headers.
Anybody ever try a header with a flat 4 collector anstead of square 4? Just wondering if it is a good or bad idea.

Re: Sbc headers.
It's been tried, not such a good idea.

Re: Sbc headers.
I have used them but only for ground clearance issues. No way this is going to improve performance.

Re: Sbc headers.
On the subject of collectors, I have a pair of 4-2-1`s. I thought about merging them to a cheap set of headers. Thoughts ?

Re: Sbc headers.
If you can get them phased correctly they may show you something.

Have you tried them? I got a pair from Wojo when I got his old wagon.. He said he never used them. I did put longer collectors on, per Al Peters, and that was worth .05 I expect it would pick up the bottom, but how much? |

I'm still using my Flowmaster 4-2-1 collectors, be for warned if you're going to use them with a " tight " lobe seperation , they don't work well with that. The flowmasters seem to like a little wider lobe seperation angle. The Burns style collector works better with a tight lobe seperation. At least tha'ts what I've found over the years, and you have to try some adjustments to get everything from them. Respectfully, Henry Kunz 1534 H/SA
