i bought a B&M deep pan once, man that thing was low, barely missed the ground. i bought a TCI pan as a replacement. much better clearence & held about the same as the chrome pan. i bought a Summit pan to add to my collection of bits n pieces to build a spare race trans. the Summit pan is about 3/8" shorter than the B&M. the B&M is rated 4 Quarts, the Summit must be close to 3 n a bit even tho they say 2 quarts. but as mentioned, real thick casting. i'll mill mine down before it gets pushed into service.
