Well folks, I wanted to post pictures of the headers that we completed mock-up of last night, but they are too big to post (over 1.5 MB). Plus they are a little "grainy" since they were taken on an old film camera with less than perfect lighting. I will have to find a way to shrink them and get them out here.
Thanks to betterthanyou for the awesome flanges (I think I will have to do business with you some more!) that got the project started! We built them on my race engine on a stand, now the next step is to test fit them on my old engine in the car. If they fit with no clearance issues, I will send them back for "finish welding" (everything is tack welded now), get them JetHot coated, and then we'll be ready to rock and roll.
My buddy and I have 12 hours each into these things just to mock them up, but better tools will speed up the process. We made all the cuts with a hack-saw using a hose clamp to keep them square, and then cleaned up the cuts with hand files. We will upgrade to better tools for future sets to speed this up. If these work as well as we hope, we want to build more sets for others. These should work for Gen II or Hybrid 2nd Gen J-Bodies (we will just have to change the flange). The cost will be much less the JBP, but they still won't be cheap. If they get coated, then the cost will creap closer to JBP, but still be cheaper. In case none of you have tried this, it takes time and that costs some money.
I am very happy right now! They look good, and they have to flow better than the crappy factory manifolds. They aren't equal length pipes, but we tried to keep them somewhat close. There just isn't alot of extra space in the engine compartment to snake the pipes for exact equal length, especially for the front. We concentrated on smooth gradual turns and transitions. We'll learn from the prototypes and try to improve them for the "production run" (which will be limited by demand and free time). Maybe we'll be able to start turning them out in the late summer or early fall.
I'll try to get pictures out here soon, and once I get runs on the car, I'll be thrilled to post results. I'm shooting for low 14's, maybe even very high 13's in great air with a tail wind!

. I'm curios to see them.
nothing's impossible-it's just a mindset
