So maddog headers really have a SCJ flange?

I'm scraping together ideas for what to do with my exhaust. SCJ heads limit the optimal possibilities. I've "heard" that the maddog headers all use a SCJ sized exhaust flange; but this has never been confirmed by anybody running a SCJ head. Input or suggestions?

I had a set of Maddog headers and loved them. They do for sure have the CJ exhaust size. The only reason sold them was because I went to upright headers.

I too have them on a cj head. On my 78 f150 they fit pretty well. Had to do a little trimming though.

MadDog makes several different header numbers to fit the big block Ford engine in different chsassis.
The 2" Fox chassis conversion headers I have use the SCJ flange.

yeah Seth, mine are CJ flange as well. Very nice quality and beautiful welds.

If you get them Jethot coated they look sick!


The only fitment issue I had, other than the driver side front cab mount which I think every fender exit header on a 73-79 will have, is the steering shaft. I had to dimple one primary tube to clear the steering shaft.

Thanks for the feedback. When I welded up the custom mount for the 2x4 box to get the proper pitman arm orientation it actually raised the steering link angle a good bit....I'm probably okay there. Naturally, my brake lines will have to be moved but what I'm most concerned about is that my clutch linkage bracket mounts on top of the frame right there and I don't see how it wouldn't interfere.

Hey Kris, what are the chances of you snapping a pic of how your maddogs exit over the frame on the driver side?

I was really considering just welding up four zoomies per side, but in the environment I run in I'd need semi style flap caps and eight of them would just look silly imo.

Will this help? Maddog fenderwell headers

buy you a set of TFS streets or other raised exhaust port heads that cant the exhaust outwards and you will have serious fitment issues.

Its a super tight fit between the shaft and my headers. Im looking in to ways to redo my stock steering now for more clearance.

I'm using a chevy power steering box on my truck and works good.
