Slamdit, I just completed this swap. if you have ANY questions send me a PM and ill do my best to get back to you, I know all about it.
Everyone has shown you the right way so far, you need the motor mounts, the bellhousing, and thats pretty much it. just be sure to hook up the ignition properly.

extra info
I had a 79 bronco with a 351m and when it was due for a rebuild my builder suggested a 400 crank.It dropped right in for $50 cdn.(that's about $30 us lol) i gained fifty cubic inches by lengthening the stroke and great bottom end.It never got great mileage but i had the 4spd and 205 with the 4.11's.It ran great with 35's.Just food for thought.

Can't re member
I think you'll have to have the oil pan from a 4x4 351w to allow
clearance for the front axle.With a lift kit you may get around that,
but,idk.

It has the 351M in it which is burning oil by the quart and knockin like crazy.
I am looking at what it would take to put a windsor in it as all my ford buddies say it is very reliable motor. This truck is primarily a driver.
This brings me to my main question.... How involved is this swap?
I know I can put another M in it but this Windsor was always taken great care of and is in perfect shape. I looked into the 460 but it seems like alot of time will be spent chasing parts to get everything in and working.
thanx again,
Sean

Anyhow, back to the swap. I swapped my knocking 351m for a 429 (same physically as a 460) from a 1969 T-bird. It was a simple swap, bellhousing & engine mounts mated perfectly. I used the 429 oil pan as well, though my 74 F100 was a 2wd. Only change, I upgraded to a larger capacity radiator. Looking back, I would have changed the rear gears from a 3:55 to a 3:31 or 3:08, or possibly an OD tranny to get better mileage.
Regarding street performance for most situations, except heavy hauling, I'd go with a 351W as well. My favorite Ford truck engine is the 390 FE.
