The sbf ford block to bellhousing bolt pattern is the same as a 300 six. The trans bolt pattern on most of the 300 bellhousings is for the truck type (top mounted shifter) transmission, 4 and 5 speeds and is different from the smaller ford 3 speed passenger car trannies. There are bellhousing made to mate the T-5 to the Windsor block, but do some measuring first as the shifter on a T-5 is on the back of the tranny, and may be to far back for a pickup application.
