Bellhousing fitiment question

Yea, it'll all fit. You'll need at minimum something like a Centerforce dual friction clutch and pressure plate to handle the 351's torque with the T-5 bell and matching 157 tooth flywheel. The 351's didn't normally come with a 157 tooth flywheel, they came with the larger 164 tooth wheel and larger diameter clutch. 157's came with 10" clutch, and later a 10.5". The Windsors and Clevelands used the 164 F/Wheel and an 11" clutch. All the T-5 bells use the 157 tooth F/wheel.
