he has the wheezer in it already...but with a bad head.
For a 400 you would need to get a 400 crank and pistons for the 351M...then rebuild it. you would need other parts to make it run decent as well.
There are 3 basic tranny bolt patterns for the c6...big block/small block is chevy terms
1. 302,351c, 351W etc, (some guys refer to this as small block)
2. 351m/400, 429,460 (some refer to this as big block- 351m/400 is not)
3. fe ie 360,390 etc (many referred to these as fords big block)
and, yes chevy did that part right...a tranny will fit darn near anything....
go with the wheezer and don't look back unless it's to put cleveland heads on it someday. (and I'm one of the biggest 400 fans)

Right now I think the 351M is pretty much out so I therefore I have 2 remaining questions.
#1 What is required to slap the C6 onto the 400? Because this is sounding easier than what I originally thought.
#2 What is required to slap the C6 onto the 360? I am leaning toward it because I know from driving it that this particular 360 is a hard running motor.
In the descriptions please include any/all parts and the cost (junkyard cost if possible). I have heard the 400 is a great motor (at least the Ford 400 is) and I would like to go with it if it wont be that big of a deal. On the other hand I have driven 2 360's and both have been hard runners. The 351W is a good way to go as well but heads are expensive. Maybe I will just get an old head machined and installed but I need to weigh all my options. Thanks for all the help guys.

Well i mentioned on page one i dont know if u missed that or not, but the 400 has the same bolt pattern as 370, 429, 460, 351m. So you have quite a bit of C6s out in the world for ya to choose.

I just meant any parts it may take for the engine swap (351W to 400 or 360). I have a pretty good idea of everything else I want on thr truck once I get in mechanically sound. These C6's that go on the 400's and351M's, do I need the whole thing or can I swap a part out on my C6 to make it bolt up? My mechanic claims he can do the 360 engine swap w/out swapping the tranny, how so?
and BTW to other responders please answer he questions in my last post before responding to this one please.

Well between a 360 and a 400 they both are in 2 totally different engine families which require that different bellhousing pattern. The FE/FT engines have a rounded pattern. The 400 has more of a square style pattern.

unless they make a special adapter plate there is no way to bolt them to different engine families. The c6 bellhouseing is part of the case and isn't removable.
What you would need to do is get a used c6 that came behind a 351m, 400, or 429 460. You can usually find decent used ones in the 200 dollar range. You will need the crank from a 400 which will probably run around a 100 or so at the jkyard. For pistons I would get a set from tmi, I cant rember what they run for price, but just link over to his website. Run an adjustable timing chain like a cloyes which is 180 at PAW. you will also want a cam and lifters.
If money is in short supply, i would build the bottom end of the motor to run a set of tmi's aussie heads and then when you get the money you can upgrade to them. Just don't skimp on the bottom end, because you will pay for it later

Just to clarify, The 400 and 360 run perfectly fine, no need to rebuild them, the only rebuilding would be done on the 351 W.

Just rebuild your 351w,that's your simplest option.I believe you can redo the engine and get a good head to replace the cracked one w/less hassle/cheaper than changing over to an FE(360) or M(351/400),especially if you're paying someone else to do it.

I think thats what I am going to try out. I called a junkyard the other day and he told me to try some kind of liquid steel to repair the cracked head. Has anybody here ever heard of it? It doesnt sound like something I want to do but I was just curious. Also what would be a good set of performance heads to throw on the 351W (for future reference)?

I dont suggest using that "liquid steel" whomever mentioned it, if its even steel in the first place. Steel expands n contracts faster than cast iron. You can have the head welded up but it is not an easy task. Cast iron takes if i remember right 2800 degrees to start melting and takes a sophisticated welder n welding machine for proper fix if its even fixable.

Yah i figured that anyway. I am just going to have the head replaced on the W and run it. Getting a pair of heads machined is going to cost me 500 bucks which I thought was a little steep but oh well, throwing some Corvette Style side pipes on her as well when the motor is done, its gonna be awesome.
