So I've been searching and have been finding somewhat some of my answers but have also been getting confused with some of the results.
I've got a '79 f150 supercab 4x4 C6 that has a 351M/400 in it currently. I've already purchased a 460 that came out of a '77 f250 which also came with a C6 transmission.
I've already decided to order the 3/4 style l&l headers and the l&l motor mounts but prior to making the order I'm trying to figure out if there would be more to orders as in the brackets and oil pan stuff...
1. The 460 I got has a power steering bracket and alternator already on it, but I've received mixed answers in regards to needing the l&l products brackets?
2. My factory a/c has never worked since I bought the truck and I'm thinking of just taking it out, is there anything tricky with doing this? It seems to buy the a/c bracket, and the two l&l pulleys is close to $400 and that would be just to keep the a/c parts in my truck that don't seem to work anyway... Seems silly as it is just a hunting truck...
3. If I buy the rear oil pan kit from l&l, should I need a different oil pump? I've read a few things that say I should but some that say I shouldn't...
4. The C6 that came with the 460, is there a way to tell if the flexplate and torque converter are correct for the engine?
There's probably other questions I have, but this is a good start.
Sorry if these are the same questions as others, but for some reason I just can't decipher out the answers... Thanks in advance!
Im doing this same swap and I will answer your questions with info I have learned.
1. The brackets on a 460 from a 2wd truck wont work. They sit too low and will hit the crossmember.
2. If your a/c dont work you dont have to install the compressor so you wont need to buy the a/c bracket but Im not sure about the pulleys. I would call L&L and ask them.
3. You wont need a new oil pump but you will need a new pick up for the pump. The L&L pan comes with this.
4. The flexplate on your 351m/400 will not work you will need a flex plate for a 460 but your torque converter will work.
Also count on upgrading your cooling system the radiator in your truck is not big enough.
Good luck with your swap. I think you'll be glad you did it once you get it al done
As for the radiator, when I bought the truck a few years ago, the previous owner said that they had just replaced the radiator with a bigger radiator... Now as with many things, who knows if that was a true statement... Is there an easy way to tell if this radiator may be big enough?

The Super Cooling radiator is the one to have. It's the largest radiator that came from the factory. The core measure 24" X 26".
Okay, now I'm slightly confused with the radiator. So the radiator is quite large in my truck. In researching the fan shroud, it says to use the D7TZ-8146-D for a 460 and that the 8146-A would be the 351M/400 shroud...
Mine says D7TZ-8146-S... So what might be the radiator I have with this shroud and do I get lucky by not having to replace it...
I'd want to see that L&L pan first. Most if not all aftermarket rear sump pans butt right up against the bell housing making it so you have no way to get at the t.c. studs. I just used a later model 4x4 pan. Summit sells the whole pan kit dirt cheep. Ford Racing M-6675-A460 .
What kind of power steering pump came on the 460 ?

I'm not actually sure on the pump, I'll have to take a look at it... The radiator piece really confusing me though. I searched last night and couldn't find much in regards to the -S in the part number...

Thanks!

Your fan shroud says D7TZ-8146-S exactly where?
Ford did not put part numbers on fan shrouds (or any other parts), just ID numbers.
The ID number is molded into the fan shroud and located on the upper drivers side corner.
The ID number is prolly D7TA-8146-S.
I've typed the correct 351M, 400 and 460 fan shroud part and corresponding ID numbers numerous times on FTE.
I would type them again, but I'm away from my parts catalogs.
Suggest you either contact FTE member jermafenser for the correct number, or wait till tomorrow night when I return home from Hawaii, then I'll type the info.
EDIT: I just bumped one of my old posts with the 460 fan shroud info.

Thanks for the info. I'll double check what the part number actually says, I probably wrote it down wrong. It is on the upper drivers side of the shroud.
Thanks for the info, I'll go take a look at the older post.
Amazing what one letter can do... I double checked and the part number is D7TA-8146-S. In searching for the "-S" I found what appeared as a post that references it for a 4-row extra large stock radiator. Now my final question in regards to the radiator, is this okay for a 460?
NumberDummy, appreciate the correction on my part number. That one has been driving me crazy! Next time I'll double check what I'm looking at.

ID Number marked on fan shroud: D7TA-8146-SA = actual Ford Part Number = D7TZ-8146-D =
Hopefully last question in regards to the radiator. Now understanding what shroud I have, I went and looked online and the "super cooling" radiator appears to be the same for both the 400 and the 460... At least based in one of the online catalogs...
Is it a fair assumption to say I only need a different shroud and can use the current radiator in my truck?

Thanks again!
That should be correct, as long as the S/C radiator is the original, and not some previous owners swap.
