Has anyone actually used the early mustang speedway motors cross member with an early sb (351W)? If so, I need some help - pictures advice, something. I just tried their kit with power rack. It was easy to install, but when it came to putting in the 351W i have all kinds of issues. I can not get it to fit. I have a canton oil pan. When the motor is back where it should be, the front of the heads are through the hood and the motor is at such an angle it wont work. If I bring the motor forward enough to clear the rack, I only have 9 9 1/2 inches between where the water pump mounts and the core support - no room for anything. HELP???
