Default 72 mustang engine swap 460 c6 from 78 e-350

my 72 mustang had a 351c 2v auto c6 w/9" 3.25 gears i still have it but block is cracked in #3 cyl, i want to put a 460 4v w/c6 out of a 78 e-350 with 67,000 miles and seams to run great. will the stock exhaust manifolds work ? what else has to be done ? has anybody done this before and did they run into any problems ? and parts list of things needed ? and can i hook up my a/c with 460 pump ? it's not a show piece, just a nice car. thank you for any help.

Stock manifolds won't work one bit.

You'll need motor mounts, a short water pump and/or a pusher electric fan, 460 manifolds, much stronger front springs, and I suggest for the love of all things automotive you convert it to four wheel power disc brakes. That 460 is going to throw that mustang down the road like a bullet from a rifle, you NEED some manner of whoa'ing it down. Stock ain't gonna do it.


If both systems are R12 or R134, the 460's pump will work. You'll need custom hoses, tho.

thanks for the info, both are r-12 need to convert, and i have power disc in front hope it will work until i can change over rear. I'm trying to do this as cheap as possible but not a hack job. when you said motor mounts did you mean off a 429/460 car ? and car manifolds ? once again thanks, anymore people out there please help if you can. thank you

Yeah, you'll need 385-series motor mounts for a Mustang. I know they exist, the hard part is finding them.


As for manifolds....don't. Headers all the way. You may only be able to fit shorties in with a 460, but if you can longtubes will give you more torque, better starting, better idle and IMO a better sound.

shortys are nice for tight spaces, but the 72 is not light on engine bay space. long tubes will work no problem. i have a set of hooker headers on my 302 right now. i love them.

If you have a welder and a cutting torch (might not be needed) you should be able to make your own motor mounts. It just depends on what kind of modification is needed.
