John, I don't know how much you want to spend, but I know of a few guys running the schoenfeld step headers with good dyno and track results. There priced right and seem to be well constructed (welds,bends, etc.) Check out there website. gsa612

Thanks I was looking at them. Just trying to get an idea what size would work best. I am assuming the 1 5/8 to 1 3/4 on a stocker would be the better size.

1 1/2 step to 1 5/8...

1 5/8............:p

Re: Header size 350ci 280hp
 

1 3/4" is a good place to start. It's a good base line. Many racers have had problems and have lost et trying step headers. I would suggest Stahl if they are still making them.They may not be the fastest but would be close. Also, Hooker Super Comps with merge collectors are a good base line.

DynaTech makes a beautiful 1 5/8" to 1 3/4" step header for that car, it comes with NitroPlate coating, and the price is excellent.

I would take the free advice form this guy. I hear he may have a clue or two about headers .

Re: Header size 350ci 280hp
 

Thats because your car weighs almost as much as 2 Novas......LOL.

Thanks for all the help. After checking with Stahl I will probably just have Jere fix the Stahl headers that I have now. Very good guy to deal with.
