never seen them before. 1 7/8 primary, with a collector im not fimiliar with.
like to get more info on them.
thanks!

 

I've often wondered why headers aren't made that way more often, or in a Tri-Y, instead of 4-into-1.

 

They are Hedman Hedders #65170. They require the use of a remote-mount oil filter and a mini-starter, as well as a stock oil pan, so I passed on them. The collector design is less efficient by a tiny margin than the conventional style because the pulse reflection is somewhat weaker between the furthest two pipes, but this is of small consequence when your Hooker/Dougs long tubes bash on the ground every time you run over a dime in the street.

with those 1 7/8 primarys, you need at least a 383 with some pretty stout cam and compression to make those work, but in that combo or anything more rad, they would work very well.

cool man. thanks for the info. i can get them for cheap, didnt know if they were worth anything. looks like they are going to be more of a chore to bolt up.
ive got a 408 lsx going in and was looking for a larger set of primaries, but im going to pass.

in the end, im going to fab up a set of 1 7/8 to replace these hawks headers i have.

 

Mabey im not thinking right, but if its an LSX motor wont it have the same style heads as the LS1's in the 98-02 f bodies? If thats right, the exhaust ports are in a totally different location than the old style blocks. Those headers wouldnt even bolt to the heads.

 

hotrod7687 is right, if you're going to an LS-based engine, none of the "old skool" SBC headers will even come close to fitting. Give Hawks a call, I've seen some of his LSx Cars with some nice headers, so if he doesn't make 'em he knows where to get 'em.
