351W to C-6 transmission
I put a "small block C6" behind an 1980 302 in a 76 F100. The bell housing should be the same on your 351W. I believe that Small block C6s came in a lot of 80's vintage Vans w/ 302, 351W and also I found my Flexplate from a 73 Cougar that I think had a 351C. I've been told that the balance counterweight on 351W stayed 28oz until the end of it's production whereas the 302 (5.0) changed in the middle of the 80's to a 50 oz counterweight. I did have to relocate my transmission crossmember back a couple of inches but that was just a matter of having a couple of holes drilled. I also had to have my driveline shortened and a different end put on it. Beware, there are many C6's for big blocks with different bellhousing patterns.

The 260 and the early 289s (first half year run) had a five bolt bell housing. Since then all 289s, 302s, 351Ws, 351Cs, and 300/240s have run the same 6 bolt bellhousing bolt pattern. There were at least two bellhousing though one to clear the smaller flexplates and one to clear the 351Cs and 351Ws on the C-4s. I believe all C-6s had the room in the bell to clear the larger flexplate. Not sure on that part though.
