A V8 bellhousing will not bolt up to a 170 or 200. Starting in 1967, Ford began using the V8 3-spd behind the 200. The block was changed in '66 to allow use for a different bellhousing to be able to mount the V8 3-spd behind the 200. This bell will not bolt up to any block previous to '66, so if will not work on your '64 170. Here is a pic comparing the 60-65 vs. the '66 and later 170/200 blocks
If you want to install the V8 3-spd behind the '64 170, then you need to use the stock 170 bell and this adapter
