I didn't want to make a restrictive manifold if I was going to the trouble of making one from scratch. Not saying it can't be done, but it sure didn't look too obvious to me!

Sad to hear your welder friend is slow. Seems to be a lot of that going on lately in all different fields. Heard from another forum member about a similar header builder looking for work, wanted me to prototype a GT header for a production run to keep him busy. I have to try to fit that into my schedule now! Of course, if he does build GT headers he'll need a source of flanges, right? Maybe I can help a few people get more paying work out of this!

I love how things snow ball together!

The more we produce the better. Cuts material costs down and everyone gets a better price.

I'll take your word that we can't make the best for both worlds with one header design. I don't have a manta yet so I can't do mock up for that chassis anyway. At the very least the flanges can be used to produce the manifolds locally.

Good to know. I planned on using it as a starting point from a modeling standpoint. Do you know what tweaks need to be made to it to make it work?
