Anybody know what year was the last year for the 400M?
Midland. Most mistakenly call it a "Modified", which technically is also true, since it's basically a modified Cleveland.jopes said:where did ford put a "M" after the 400?
hell ford never said what the "M" even stands for in the first place...
The pistons are also different. The wrist pin is located higher to make up for the longer stroke. Therefore, you can't use 351 pistons with the 400 crank &vice-versa. If you use the 400 pistons with a 351 crank, they will be too far down resulting in little to no compression. 351 pistons with a 400 crank would put the pistons above the deck, trying to shove them through the heads.fordman7795 said:there is a M after the 351 to distinguish between windsor, cleveland and modified. the 400 is still a M because its the same as the 351M except the crank.
