Headers for 460 swap in 78 F250 4X4 (*needs clutch now*)

My buddy just pitched the 400 in his 78 F250 in favor of a 460. He's having trouble finding a set of headers to fit. Anyone have any experience with this swap? It seems to me like Hooker makes a set that fits. Anyone know a part number? Here's a couple pics of him throwing some mud.

Thanks

I did that very same swap. I bought my headers from L and L performance products. At the time they were out of Wylie, Texas. The headers were Hooker Super competition. I had to slightly modify the frame on the drivers side, other than that they fit fine.
sorry i don't have a part number.

I'm sure fenderwell exit would be fine. Do you have the part number for those chilly460?

What size tires is he running? I've heard of clearance issues with fenderwell exits and larger tires.

Sanderson shorties look like they should work in a 4x4 application, and they are chassis exit.

Those that say it cant be done should say so quietly, so as not to disturb those who are doing it.

He ended up getting some Hooker Super Comps, so that issue is resolved. Now he needs to know what the proper clutch for this swap is. Our local NAPA guys told him to get a clutch for a 390. That doesn't seem right to me. Anybody have a part number for a clutch that will work?

Thanks

Use a 390 flywheel (if its a neutral balance 460) a 400 diaphragm clutch, and a ring gear from L&amp;L. Pilot bushing from a 400 will fit the 460 most of the time as well.

Not all 390 flywheels are created equal either. Look for one for an HD application (which is also the same as early hi-po stuff), like say a 73 F-350 dually or something. YOu'll know you have the right one if the 400 clutch bolts up. IF it doesnt, you can either keep looking for the right flywheel or get the smaller clutch, which I believe a cleveland application will work and get you the diaphragm clutch.

Most importnat part of all of it is the diaphragm clutch. The 400 bell isnt deep enough to clear a 3 finger clutch.
