Wanted: Exhaust Manifolds AMC v8

I have tears while i type... ive realized that my headers on my AMC 360 are in the way of the steering shaft leaving me to go back to the standard exhaust manifolds... of which i tossed at the rolling chassis stage of my restoration (space was tight in the 1car garage).

Anybody have a couple of these paperweights in a bin somewhere? :(

I have 2 old waggy's with 360's in them. One is a 74 the other is an 86. I have no idea what shape the manifolds are in or how easy they will be to get off. If you are interested let me know.

Thanks for the replies guys. I found my manifolds at my bros-inlaws place, put one in place and steering shaft path is still blocked.

might have to look into altering my header, or seeing whats changed that could have created this issue (engine is new - but the same, swapped a 304 for a 360, steering box is in the right place, just with a MORE bracket now, added 1" body lift ), uggh just when i thought i was ticking things off my list...

Mud Lite, altering the steering sounds scary... perhaps not for the naturally mechanically inclined ;) and it doesnt make sense that this isnt working, the only thing that changed was a 1" body lift, swapped a 304 for a 360. Im pretty sure now after seeing the manifolds on Nick D's CJ, that its because the Pacesetter headers no longer work with a body lift incorporated, and the manifolds i have are different than his, so i need to find the smaller 304 type ones with the exit in the middle of the header.

hey kbrousseau, do you think any of them look like the attached, where the drivers side exits closer to the middle rather than the end, which is what came with the engine and dont quite work, and also come down right over the clutch linkage.

Heres what im looking for:

Looks like an easy enough fix with a BFH . Just heat up the header with a torch and hit the offending area with the ball end of a ball pein hammer .

It could look totally different in person , but in the pics it looks as if it is do-able .

I dunno, I'd be leery to make hammer clearance on the header. The engine is going to rock back and forth in its mounts as well and to make enough clearance the runner is going to be very compressed which will affect flow, etc., etc.

John may be on to something with the extra pillow mounts/joints. Investigate it a little. IIRC companies like Flaming River may even make vehicle specific kits for this problem.

The most "elegant" solution is a different header though.

I can check the manifolds some night this week, If I remember right though I believe the drivers side dumps out the back of the engine.

If you are lookling for a home made fix. Pillow block on the frame and another u-joint shoul do it.

mount the block to the frame, run a shaft from the steering box to it, then a u-joint and another shaft to the steering column.

I was thinking you could modify the header so that the tube comes out around the shaft. I pretty sure Lou form Muscle Car used a set of headers like that once.

I got the 360 mainfolds on my CJ7 with a 2 inch body lift, its close, but they fit, maybe it is the steering brace? Also, my manifolds dump super close to my frame rail on the drivers side, anyhow, I heard a quick rumor, that you could mount them on the opposite sides so the dump is at the front, to keep them clear of the frame rails. and maybe the steering shaft? I also heard that the 304 manifolds fit WAY better. But anyhow, i never tried or gave much thought to switching mine around but maybe it will work? worth a try its free to test fit.

Thanks Caveman, Andrew had sugested the hammer solution at one point too, but i guess the pics dont really do it justice, in the last one the end of the shaft actually sits about 1.5-2" outside the end of the column, and an 1" or so below.

Ive come to the conclusion after trying several options for mounting the column (ie 1" of spacers, a misc bracket I had lying around) that the Pacesetter headers just dont work with 1" of body lift.

Right now the two real options im considering are, finding oem 304 manifolds and ditching the pacesetter system, or getting that first tube reworked and out enough for the shaft to run through it.

If I cant source the manifolds, or if getting the header hacked up wont work, ill look deeper into the pillow mount. I recently got a borgeson shaft and they have a diagram and some info on going that route, perhaps ill ping them tomorrow to see what's involved.

Thanks for all the input guys!

Thanks Keith, if you could look. The manifolds sitting on my floor dump out the back of the engine, thats no good, i need the other style for the 360/304's that dump near the middle on the driver side... not only for this steering mess, but I think, that with the dump at the back of the block, it puts the exhaust pipes right into the clutch linkage

I think you put a jihad on my build at my old house ?*and thats why you have that nest on your face! This way you could be done before me!!:finger:

Thanks Dirk, im going to get in touch with Borgeson tomorrow to see what they have, and if going this route means my shiny new steering shaft is useless for the application and what else I might need

I checked my two FSJ's last night. The 86 is a rear dump but the 74 has the manifold you are looking for on it. :) It also has pollution tubes on it that would have to be plugged but that is not a real big issue.

When Kaiser built Jeeps in the 60's they ran the same manifold left and right on the 3.7 and the 327 as well. This dumped the exhaust out the front on the drivers side, so it has been done before, even from the factory.

Lemme know if you are interested in it.:beer:
