Gen III motor guys (LS1 based 4.8/5.3/5.7/6.0): header poll

Seems like now that everyone is discovering these motors they are finding their way into anything and everything that moves. Including our trucks. Because I have a hard time shelling out 800 bucks for a long tube header designed for a 67-72 with a LS1 based motor I am building my own set.

I was wondering if there is any interest in a more affordable header if I was to produce a limited quantity of these? I'd like to know a few things:

1.) A head count of people that are first off, even interested in a set of headers for their LS1 based 67-72 truck, in the near future.
2.) What qualities would make the header most desirable - bearing in mind these will affect cost. (materials like stainless or just heavier guage mild steel)
3.) What is the most you would be willing to pay for a set.


The set I am building for my personal project will be using 1.75" primaries with a 3" collector. Nothing fancy just a nice and thick 3/8" flange for the heads and tig welded. I have the ability to construct a header from any material starting at mild steel even to titanium (bring your wallet).

I made a set of F-body headers fit once but I had to hack them up pretty bad, so I am finally biting the bullet here. Going from manifolds to my previous long tube headers I gained 26 rear wheel horsepower and 22 ft pounds of torque. You should expect that much with these with a good tune.

Let's hear some feedback...
