From my knowledge it stopped with the 450. The major difference between a 400 and 450 was the 450 had 4 1/4 pistons instead of 4 1/8. The 450 also was painted with a white front grille and some on the sides instead of the 400 which was all red. Some of the late 400 blocks where capable of using the 450 sleeves, but I don't remeber the serial number break of the top of my head. Just for completeness, early M's were 3 7/8 bore and later M's where 4". SM's were 4 1/8. The main difference between the non and super is disk brakes vs band brakes. Don't forget about the SMTA's which were basicly 400 chasis with SM style tin work. The hood on a SMTA is about an 1" longer if I remeber right though. If anybody finds errors in my specs, please let me know. I have rebuilt several of each, but I just woke up a bit ago and its too early for math numbers! My stepson and I just hauled 28 old farmalls to the American Threshermans Show in Pinckneyville, IL yesterday (and early early morning). Hope this helps.
