351w bolt pattern(bellhousing)
I need to replace my 351w(5.8 liter) in my 1985 f-150 but am having trouble finding a motor to bolt up to my c6 bellhousing! I heard that a 302 would work but cant find one with same bellhousing bolt pattern.How many different bolt patterns are there on the 351w or 302 block?

Are you sure it is a 351W? I think there is a slight possibility of it being a 351M, which has a big block bolt pattern. All the small blocks (300, 302, 351W, 351C, etc.) should have the same transmission bolt pattern.

Unless you happen to get hold of an old 221, 260, or early 289 with the 5-bolt bellhousing!
But other than that I think Eric's on the right track, you probably have a 351M which limits your choices to the 400, 429 or 460.

small block
I know I have a small block engine but what I cant figure out is my top two bellhousing bolts are only 5" apart?I looked at a 351m and the top two bolts were alot further apart,also looked at 302 and they were also futher apart I'm lost!Thought it was because of tranny dont know.
