Full length headers on '94 302
Does anyone know why full length headers are not supposed to fit a '94 302 with standard transmission? i'm replacing my I6 with a 302 and would like to know if the modifications that have to be made are serious. Help please!!

Well LexLuthr69 on FTE (here) has Hooker's on a 302 with a M5OD trans. Unless the frame changed when the body did (which I highly doubt) they should fit.
I have Hookers on a 302 with an AOD.
I'd say order them and see if they will fit you can always send them back and go with some quality Mustang short headers like BBK's or FMS.

Hit Man X,
you'll have to forgive me. is the M50D the 5 speed standard? i'm a little green on the tranny codes. i take it this other guy must have an 88-91 does he? thanks for the info guys. i'm 19 and this is my first shot at an engine swap. not the last, just the first. thanks again.

The peeps with lots of mods seem to be 87-91 (older body) years to me. Like I said I do not see why that stuff will not work...all you can do is try as this is pretty much uncharted water when building an older truck with different non direct swap parts.
Hey being young is fine, I am too! lol. I am sure this site houses ages from 16-60 or more.

Then after it works again I become:
Just ask up, I am sure most of what you have planned someone has done before to some extent. Anything performance bolt-on related as me...I have everybolt on minus electric fans. I am waiting to get my larger alternator before doing them. I already have the fans and controller.

i have another question for you hit man x. you say you have a set of hookers on your 302 right. here's a biggy. are you able to keep them tight? if so how? nobody i talk to has ever had any luck with the age old battle of header bolts. also, what did you do with the O2 sensor? i wondered if the coleector/reducers with the O2 bung are a good idea. what did you find worked best?
P.s> thanx for the patience!

Torque them to about 15ft-lbs also. I start with the front and rear bolts when torquing.
Also I do not drive the vehicle for about 24 hrs so that the Lok-Tite can setup and cure.
I did this when I ran shorty headers and never had them leak in about 1.5 years. Pull the bolts right back out and installed the LT's with no problems on reinstallation. Now months later still no leaks.

And, if you don't mind me asking, the O2 sensor? By quality gaskets you mean copper between the headers and the head?

The moderators keep turning off my User Gallery for some reason I need to have some words with them to see what exactly the problem seems to be with my pictures.

I would add a MAF system before doing a cam swap...it will only be better with a MAF setup.
What year engine harness did you use?

To tag along with what Hit Man said, by directly measuring how much air is coming in, the computer is more accurately able to pump the amount of fuel needed into the engine. With Speed Density, the computer gets it's main reading by measuring the amount of pressure inside the intake to determine how much air is flowing in. An indirect measure. It works (obviously), but MAF is much more efficient.
As for the long tubes, I had to tap in one of the primaries on the passenger side for it to clear the frame, but Hit Man had no problems with his. I hazard to guess that mine is probably due to some aging motor mounts, but I'm really not sure. Also be prepared to have someone fabricate a Y pipe back to the stock exhaust, or better would be to just gut everything back and run some hi-flow cats and better flowing mufflers.
Good Luck with it.
