Headers
I was hoping someone could help me with header choices.
I've got a 1982 f100 with a 1985 302 and we swapped in an m50d 5speed standard tranny.
I'm not sure if I should use headers for an early 90's truck because of the tranny or if I should use an early 80 set for the rest of the truck.
Anyone else with this swap work it out? We want to go with headers that bolt to the stock exhaust if possible.
Also I'm getting custom dual exhaust run out to the back so does it matter what headers I get? Anyone running longtube headers and still doing emissions?

I put factory ford fox body mustang shorty headers on my '86 F150 with a 302 and just bought a weld on bung for the O2 sensor and welded it into the exhaust pipe. I went with these because I found a set for $10 and the manifolds fell apart when I took them off. I rewelded them on the outside and ported the welds off the inside of the headers.

Ah yes, the 302. I have BBK shorties on my stroked 351W. Of course, the 351 block is taller, so I had to trim the firewall just a bit on the drivers side to provide clearance on that side. It happens.

Nope, theres plenty of room behind them, I didnt trim anything to install them. The tightest fit for them on mine was at the cross member area because the headers had the tubes the went to the air cleaner, but it all clears and is a great solution to cracked manifolds. I didnt know if they were going to work when I bought them, but for $10 I figured I could take a chance. I'll get a pic tomorrow.

There is a set of bolt on shortys available for the 87+ trucks that fits the stock y pipe, I believe there is even a summit racing branded cheap version.
My 81 F100 years ago had a set of mustang shorties on it's 302, they fit just fine.

I've got the Summit version, and they do dump to the stock y pipe location. Great option if you can only do your exhaust one section at a time.

Just an update guys.
I ended up getting some ceramic coated Foxbody mustang headers. They gave plenty of room and were pretty easy to install. The old boy has got headers and dual exhaust with thrush welded mufflers and high flow cats now.
Sounds great and has a bit more pick up too!

did you have any trouble getting around the clutch linkage? I have a 302 that had a 3 on the tree but has been converted to a floor shift and I have heard that headers hit the clutch linkage. or is that only the case in long tube headers?

My Firewall didn't have the dimples where the holes needed to be drilled for the clutch master so I took a piece of paper and drew a template of the holes on a junk yard truck and transferred it to mine.
Also if you have a mechanical clutch now the end of your clutch pivot/arm thing under your dash will have to change so pull that also from the JY truck. You want to get a trans tunnel also if you can find one.
The neutral safety switch wasnt necessary in my truck but you should probably in stall it. I helps the clutch return anyway.
