I know nothing about Hudsons but I do have a 1972 Clifford Hudson catalog. On the first page it says that the 202 is 4" shorter than the other engines and because of that no parts interchange except lifters. The only other mention in 15 pages of Hudson parts and information of the 202 is a listing for a rear main seal. They made 104 hp with one carb and 114 with two.
