Default Large tube headers for 434 SBC in 3rd gen.

Does anybody offer a set of 1 7/8" into 3 1/2" collector or 1 7/8" stepped to 2" into 3 1/2" collector headers that have a Stahl flange bolt pattern to fit a 3rd gen chassis? I do have the Spohn tubular K member, A-Arm and coil over kit to free up a little bit of extra room. Anybody know of anyone that will build this for me as I'm sure no one has such a thing already built. The 1 3/4" Hooker Super Competition headers that I now have will just not be enough for the 14:1 N20 434 motor that's going into the car. Thanks in advance for any suggestions or recommendations.

Thanks for that info. I'll call them on Monday to see what they really do have.

Hedman makes some large tube headers but not for the 3rd gen chassis. Only altereds and dragsters. I wonder if the altered headers have a chance though...

And I probably should have just done a big block like Juiced96Z. For the money I'm investing in this 434, I could have had a 1100+ horsepower N/A 632. Oh well, having a nasty small block is cool too. I've just got to get the headers to make the power I want out of it.

Any other suggestions???? Thanks in advance.

Yes, they do make a set for a small block in a 3rd gen. You're absolutely correct on that one. They have 1 5/8" primary tube diameter though. Unfortunately for me I need some 1 7/8" or larger. I wish Hedman made what I'm looking for as their products are usually quite economical .

xpndble is right on this one. they have ANOTHER set, under the Hustler line that is a 1 7/8" primary with a 3.5" collector. they are one badass looking set of headers. i can't remember the part number though. give hedman a call.

Headman does make a large tube header stepped. look at there catalog. part # 65175. They have a few more parts #'s Goto headman web site. Click race headers, then street and strip.

Thanks guys. Time to do a little more searching on their website. I went there but obviously gave up too quickly.

*EDIT*
Oh man. Sincere thanks to everyone. I found exactly what I was looking for once I clicked on the right area of their website. 1 7/8" stepped to 2" with the 3 1/2" primary. It says they're a race only header but this is obviously not a street car anymore. I'll call them on Monday to verify but this should be exactly what I'm looking for to support 700+ horsepower on the motor and 900-1000 horsepower on the N20. I love it when a plan comes together.
