Try Hedman's 88-650. Either Jeg's or Summit carries them. I think those are the ones that Corpse has on his car.

those are the ones i have on my car too, the only complaint i have about them is that the 2 rear bolts on the driver side are a royal pain to get in, but other than that they fit really well. do yourself a favor and get either the copper or aluminum gaskets because i guarantee you won't want to change the cheap paper gaskets when they blow out. i would also have the collector flanges and the head flanges welded around the circumference for extra insurance, i wish i would have done that to mine, but i haven't had any problems so far, so i guess it's not critical. they are a drastic improvement over the stock manifolds for sure. if you can't afford the coated headers then at least have the painted ones sandblasted and paint them with VHT cast iron 1600* header paint, i did mine almost 2 years ago and they still look very good. pm me if you need anything.

I've got Heddman shortys on a 302/AOD comb in my '70, and they fit perfectly, with no mods to steering or the tranny. I like them enough that when I go eventually go with a 351W, I'll get another set.

Not trying to talk you out of it but...why shorties instead of long-tubes? Is your car that low to the ground?

The AOD pan is a lot wider then the C4 of FMX. Not all of the long tubes will fit around it.

Yet another item I have sitting brand new in the box that I will not longer be using LOL

Yeah those headmans look good and recomend them for a budget. But there is nothing like the JBA's or the 1 3/4 anderson shorties I plan on getting, which I almost got till someone showed up and bought them hours before I got to the place grrrrrr.

I have a 1969 coupe, im guessing their pretty similar. But i have a 351c in mine so i installed the long tube. Brought it to a muffler shop one of the pipes had to be bent around. I wasnt able to use shortys. I used hooker competition headers. Not sure if this helps you decide or not.

After seeing longtubes take ~20 hours to install in a 2001 WS6 I would say yes, there's PLENTY of room in there

The only place it is tight is where it gets near the underbody bracing that is only an issue with a convertible. I say it is tight but not so tight as to cause any real problem, although I'll have to use an H-pipe since it does make an X-pipe too difficult.

Long tubes are generally a little better for performance (everything else being equal of course) but the long ones will take away some ground clearance. Not much of an issue unless your car is lowered more than the typical 1-2 inches though. The clearance issue on my car is BEHIND the headers, and that will only happen on convertibles since their underbody is quite different. Your 72 with a 302 should not have any problems with putting an X-pipe on it.
