I have heard of problems with getting headers to fit in Mavericks. I am about to swap in an 83 302 into my '72 Mav. Are there any headers that will fit without any modifications? Will shorty headers fit? I'm 17 and just don't have the experience yet to do things like this without help, so I would REALLY appreciate any advice. Also, where can I find the Mav. motor mounts, engine crossmember and trans crossmember? These are the only parts that I am needing. Thanks a heap! Preston
Hedmon #88-400 shorty headers will fit as long as the trans is an automatic and floor shift. The stock iron 302 manifolds will also fit.
I am planning on doing a fairly similar process to my car. I am going to rebuild my engine with the 83 parts. I already bought the carburator and egr spacer. I will get the intake manifold from edelbrock. The camshaft I can get from napa (the cam in the 83 mustang was much more aggressive than the one that is in my engine). Does you car already have the 302?
At the moment I have the original 200 and C-4 trans. I'm in the final stages(I hope!) of preperation for the swap!! It looks like all I am needing is the motor mounts, and a V-8 radiator. I may need the engine crossmember and the trans. crossmember, but I'm not sure if those are absolutely neccessary(Could somebody tell me?) Anway, I'm excited. Thanks for the input, please keep it coming!! Preston
Maybe I can help with the motor mounts. I'm pretty sure the blocks are almost the same so when I get my motor mounts, I am going to get them from napa. They are about 30 bucks a piece. The only other thing you might consider is the oil pan. I know in my friends '84 t-bird the pan has two drain plugs and apparently a different oil pump location.
We have heddman 88-400's on our car, it's a shorty header with 1 1/2" primary tubes and 2 1/2 collector it's made for the falcon with a colum shift. When we first installed these header we had an automatic with colum shifter it cleared everything fine although I did have to trim some flashing off the bell housing on the drivers side I also had to make a small dent after the collector on the exhaust pipe to clear the pitman arm at full lock. Nothing major and the muffler shop should have no problem doing this (the dent). It should work on manual cars also because the Z bar mounts in the same position as the colum shifter pivot but, I'm not 100% sure about that. We have a t-5 now with a hydraulic clutch and a mustang II front end so no problems with clearence. A front sump pan is what you need the rear sump pans are for the late model car that have the steering in front of the wheels. The oil pump is in the same place but the pick-up tube is routed to the rear of the pan on the rear sump pans. They also have two drain plugs one for the main sump area and the front one for the oil pump area.
Thanks everybody, I'm soaking it all up! Oh, and David, thanks for the motor mount info., I'll have to check on that! Preston

I tried the 88400's on my '72 and had problems with the drivers side outlet being too close to the manual steering box to get an exhaust pipe hooked to. Think I'm going to try some tri-y headers next, should give a bit more ground clearance than regular full length hookers I've got on now and probably not interfer with anything else (I hope!). By the way, if anyone would like to try the 88440's, I would sell my set for $75. They are in nice shape, no mods. Let me know if anyone is interested. I wouldn't be able to ship probably until after x-mas, since I'm currently in PA and the hedders are in IL. and I won't be back in IL until x-mas.
yes, I will also add that those 88400 shorties are a tight fit. Passenger side is ok, but driver side gets real close to the steering gear. BTW in case anyone's wondering, no they wont fit upside down and facing forwards---or just turned backwards facing forwards. Already tried it. Hits oil filter one way, and the long rear primary tube hits shock tower the other.

I also have the 88-400 on my Comet with floor shift automatic. I to, cleared a protrusion from the bell housing. I went a step further and redirected the outlets downward to make a much eaiser fit and access to the head pipes. The end results are lots of working room around the transmission on both sides. There are no clearence problems with this change. To do the change, cut 3/4 of the way through the outlet end 1" behind the flange (from the top). Spread the cut open 3/4" and weld a patch over the gap and fit head pipes from there. You will like the end result. Sorry that none of these parts are a bolt on without some alterations but thats how it is when changes to a car are attempted.
I see the 88400s have been tried with manual steering and floor shift, but how about power steering and a column shift?
I don't know about column shift. They don't come close to any power steering parts. I will say that the out let fit on the steering side will come very close to the steering box 'arm end' when the steering is turned 'full left' but can be made to fit ok without a problem if pipe not more than 2-1/4" is used and the change is made as I explained above. The header outlet size is 2".
That's what our car started out with as I stated in earlier post. I didn't have any problems with the steering box, only when I installed them if I remember right I had to jack the left side to get the headers in. I went with these header because the car sets so low I didn't want to have the clearence problems that could have present with full length headers. We now have a mustang II front and a T-5 trans so we have no clearence problems.
