| Bellhousing is 385 series and 351M/400 small-block |
Small-block Fords have been produced in displacements ranging from 221-400 ci, but as you might guess by now, there were a number of different series of these engines. The 221/260/289/302 engines were the Fairlane series, and then there are the 351 Windsors, 351 Clevelands, and finally the 351M and 400s. Interestingly, some aftermarket suppliers don’t classify the 351 Cleveland or the 351M/400 engines as small-blocks, presumably due to the large, canted-valve heads. But since they feature the same 4.380-inch bore spacing as the Fairlane and Windsor engines, and Ford Racing Performance Parts classifies them as small-blocks, that’s good enough for us.
