ok my dad has a 75 f250 with a 390 thats been dead for yeard he really misses his truck and his b-day is comming up so i wanna get it moving again for him :).well the 390s dead but i picked up a 72 2wd f250 with a 460 4v moter what will it take to put this in i have both trucks complete so i need to know what moter mounts/bellhousing/tranny and anything else you guys can think of. thank you for ur help guys :cool2:

What transmission does the '75 F250 have in it? Are you sure it isn't a 360 in there now, not that it matters. If you have a Manual tranny, you will need to get a T-18/NP435 Bellhousing for a 460. If it has an auto, you have some work ahead of you. You will need to find a 2wd C6, then attach the t-case shift levers to it (if possible), mate it up to the intermediate shaft to the t-case, etc. Motor mounts/headers/manifolds will all be tough as well. I believe L&L makes a kit that makes installin a 460 easier than trrying to find all the stuff in the boneyars, but its spendy.

Hope this helps ya a little bit.

just rebuild the 390. save yourself the headache and money.

well the 4wd f250 is an auto but its got a divorced transfer case so can i just use the engine and tranny out of the 2wd f250??? the 390 is froze solid and ppl have been taking parts off it for years

Yes you will be able to put that motor and tranny in it. You may have to modify the shaft between tranny and transfer case.(lengthen or shorten)

ok so what about the moter mounts can i use the ones out of the 2wd ??

If those 2wd mounts look like the ones in L&L's kit you should be okay

I think its the E-series oil pan and manifolds that work in that frame. Not 100% sure.

72 Ford trucks didn't come with the 460. Reverify that you have a 460.
They came with straight 6s, 302, 360 and 390.

Yea, & nobody is smart enough to have possibly swaped one in, :flipoff2:

After verifying you do have a 460, the swap is easy,

For motor mounts get the 2 bolt 390 mounts from napa, the mounting holes & the stud that go in the frame perches are in line, you'll have to elongate the mounting holes in the mount a little, then bolt them to the block crooked, (I know this sounds a little jerry rigged) but the napa motor mount are $25.00 & the L&L moutns are $69.00 & I've had better luck with the 390 mounts,

If you are comfortable with disassembly & reassembly of the tranny you can swap tail shafts & tail shaft housings & not alter your mid. d-shaft,

I'm not sure but I think with the older 3/4 tons (high boys) you can run the front sump pan & it will clear everything,

(edit) If you need a set of headers I have a set of L&L fenderwells that will fit that combo (shameless plug I know)

are the L&L headers worth it?

sorry for the thread jack

sorry for the thread jack

I'm not picking up what your putin down, ,,,,,,,,,worth what?

re use the stock manifolds unless you are made of money

compared to other headers not manifolds

yes they are worth the money if you find a nice set used. They are pretty heavy, about 75# for the pair, VS. a cheap hooker comin in at half the weight.

Where is shit springs anyways??

For a mild build, up to around 550 hp they are a very good header, I have heard stories of poor quality, but I have two sets & seen several others, all that I have seen have been very good quality,

plus with the fenderwell exit it is easy to run the exhaust & it keeps the heat away from the oil pan, tranny, & t-case,

ok well it looks like ive got a lot more to checkout on these two trucks thanks for all the info.and i checked the 2wd one and its a 73 not a 72 sorry so im trying to take the engine out of a 73 2wd and put it into a 75 4wd.and shit springs is really called silver springs its out by lake lahontan

ok so putting a 460 into a 75 f250 4x4 is such a pain in the ass lol why couldnt ford keep anything the same do they hate the backyard mechanic that much ??
