i was wondering if someone could decode these water pump housings i have 3 or 4 of them , they are all alum and the casting numbers are 2536767 and there are xx on a little what looks like a tag but looks like part of the housing as well also another number on the housing is 2205862 also they have water pumps in them and the numbers on the pumps are 2843290, sorry i don't have any way to post pics of these housings right now but will post at a later date. was wondering since my intake manifold is from a 64 hemi that these housings may also be from the same car? thanks in advance.
