Hey all been a long time since i posted here. Sadly had to let my beautiful 78 2wd go a couple years ago but i just acquired a 78 f150 4x4. Has the 351m c6 combo currently. Needs alot of love as its a michigan truck and has seen its fare share of salt and neglect. But alas shes mine. The 351m has a rod knock so ive sourced a 460 out of an 84 f150. Ive researched the swap and am aware of what i need my only question now is will the 351m starter bolt up and work with the 460 or do i need to grab the one from the donor truck? I'll have the torque converter and motor mounts etc. Just didnt know if the starters interchanged or not. Thanks in advance. Feel free to comment any tips and tricks for the 460 swap. I'll post some pics of the new truck soon. I picked up a bunch of original ford goodies from the junkyard today. Mint grill shell a wondshield visor a set of stock hub caps and other misc. Lights i needed as well as a nice set of door pads as mine was missing the passenger side. Oh and if anyone here is from michigan im trying to source some more parts if anyone has an abundance of parts trucks.

Here she was after i weed whacked the 64 ft. Of grass from around it. This used to be my wifes but her ex took it when they split up. Told the guy when i got it its sad cause now ive got his house his women and his truck its like a bad countey song haha

Heres my original love. Im going to model the new one after this one.

 

A great info source https://www.projectbronco.com/ Scroll down to the technical link. Then see the engine link....

Starters & Distributors --Before you drag your old 351M/400 engine to the beach house and install your new anchor on your boat, pull off the factory distributor and the factory starter. Why? Because they will bolt on and work perfectly on your new 429/460 engine. If your 429/460 has a points-type distributor (most pre-1975 engines) then you should reuse your Bronco's Duraspark II electronic distributor. It will really bring that old 429 or 460 to life! Also, your new engine may have a bad starter on it or may have not come with one at all. You might as well save yourself a few bucks and use the Bronco's original starter.

One other neat little item you can use on your 429/460 is a 92-93 7.5L F-Series gear-reduction starter. They are smaller, weigh less, and have more torque than the standard full-size Ford 351M/400/429/460 starters. If you plan to install headers on your Bronco with a 429/460 engine, then the gear-reduction starter will give you a little more room to work with in a cramped engine compartment."

Is the doner truck a 4wd? Make sure you have the correct rear sump oil pan.

 

Yep as posted above. 351M/400 and 460 starters interchangeable. I have a 92 460 with the PMGR (newer style) starter. Not a fan, I like the older larger ones better (yeah, I'm the one).
Also - unrelated to your question - when Ford went to PMGR starter on 460 in 92, they differentiated / had different part #'s for auto vs manual trans. Never have experimented or gotten an answer as to which version is comparable to older starters - which were identical for auto vs manual. My guess is the PMGR manual trans starter for ZF trans is what's different. But that's just a guess.

 

donor truck is 4x4 as well. I planned on swapping the oil pan as well. It'll be awhile before I can put the 460 in anyway i plan on swapping pans and painting and refreshing the upper gaskets etc. Thanks for the info I appreciate it. Im hoping the 460 manifolds will work if not ill pickup some headers.

 

Since your doner vehicle is a truck you should be ok. It is when the doner vehicle is a car that you can run into issues of the exhaust manifolds being to short and a frame contact comes up on the passenger side.
