Code H stands for 351M not a 400.
400 is code S
I don't know what you would use for a flywheel for that 460 as they never put 460's into 4x4 until 1983.
I also don't know if they had manual trans hooked to 460's then in 1983 either.
You can ask about the cost of rebuild in the 385 engine series forum.
I suspect about $1500-$2200

If what you want, is cost effective, then you would be farther ahead to rebuild your 351M into a 400 with performance mods. I'm not trying to stir up a hornets nest, but... a 400 that is properly built, will out perform a stock 460 rebuild, and all the cash you would drop into the 460 conversion could be used for making reliable power with the 400. If you search the 335 series engine forum, you will find tons of info. on how to build these engines the way that Ford should have done it. TMI is a sponsor who has built many of these with alot of success. You can check it out at www.tmeyerinc.com
Again, I'm not knocking the 460 in any way, as it is a great engine. If being cost effective is a concern, then rebuilding your current equipment will bring the desired results for less money. I would rather spend money on the engine itself, than to spend it on brackets, adapters, special headers, and such that do nothing for performance or fuel economy. Just my opinion,though.

Million, thanks for that link.
That is what I was trying to say without looking up all of the tech stuff. That article pretty much sums it up. Dollar for dollar, you would be farther ahead building a 400, than to put alot of your money, time , and effort into swapping in the 460.

All in all the swap isn't hard to do. I swapped my 400 for a 429 earlier in the year (same swap as your 460). Used the L&L mounts and fenderwell headers, this their was $600 or so there. (headers were well worth it!!!)
Rebuilt the 429 myself, about another $500 after getting a edelbrock performer intake. Mated it up to my C-6 with no problems. From what I understand with the standard trans needs a 1/2" spacer plate between the block and housing for clearances of the clutch. Their's a few guys around here running 460's w/the 4spd in their 70's.
I reused all the 400 accesories, ps pump, alt, fan, only pulleys I used from the 429 was the crank pulley.

I know a guy I used to work with that had a 77 F250 4x4 with a factory 460 and a 4 speed. The only one I have ever seen though. They did make a flywheel for a 460. I actually have one in the garage.

Truth be told, the 460 is not too painfully expensive to do. Unless you love shifting, I would ditch the manual for a c6 and a matching t-case from a similar truck, but they do make flywheels for the 460 and I too have one sitting in my yard holding down a tarp for the winter. I wouldn't say that they are rare by any means. If you're serious abuot a I would find a 460 with everything still on it as far as accessories go. Next, rebuild it "right" as someone stated above. I am pretty sure that you will have far more horsepower and torque then you ever will with the 400. But, don't get me wrong, it is going to be more expensive than rebuilding the 400.

IMO, build up whatever you already have, unless you can get a 460 pretty cheap. Rebuilding whatever engine you have can be as expensive as you want. As far as the swapping goes, it really isn't that expensive if you really want a 460, but if all your going to do is rebuild a 460 to stock specs, than I don't think its worth it. A 400 is just fine. I myself am going for a 460 (521 stroker) in my 77 F250 4x4 and a C-6 tranny.

The thing about the 460 is the year of the 460 and how many stock parts is on it.
A 1970/71/72 460 has twice+ more HP and scads more torque than a 76/77/78/79 460 in stock form.
That's how 360-380 HP (early 70's) compare to 212 hp (mid to late 70's) ?
MB can clarify the things needed to spruce up the later one.

Dennis, you know that figures for hp being twice as much for early models is based on false a premise. the early ones were brake HP, the later were Net HP, measured different totally. Truth is the early engines if measured the same way as the later model engines were actually only about 250hp, so although slightly higher not nearly as much as people think.
As to spruce the later models up, thats another thread entirely, and probably should be in the appropriate forum so if you decide to build an engine put it in that forum for that specific engine family. IE if you want info on the 460 I will be happy to answer down in the 385 series engine forum.

Yes I did 
The major thing is efficiency of the 2 engines.
You know that so many people complain of 8 mpg loaded or not in the mid to late 460.
and yes the 385 egnine series forum is the best place for discussing it.
I went with my 429 for numerous reasons.
The condition of it / price of all the parts included and a free facility to do the swap.
Otherwise, I would have re-done the 400 that was in it ..... like I keep mentioning.

If you are rebuilding the engine anyway- as is the premise in the original thread. It reallly doesn't matter what the thing is all that much. All the heads work well when ported, and the blocks are about the same. The most important part of the 460 build-up is in the heads....get trickflows if you really want it to scream.
