I have a 55 F100, 223 six, with a three speed trans. I also have a 56 F250, 272 V8, with 4 speed syn. Will the 272 bellhousing bolt to the three speed,or will the 223 bellhoushing bolt to the Y block? I want to put the Y block in the 55.

 

you need a truck 3 speed bell,for v8.all the way up tp 64 will work.
