Guest Bob Call Posted December 6, 2007 Share Posted December 6, 2007 I'm trying to sort out the foundry code marks found on Chrysler, DeSoto, Dodge, Plymouth, industrial and marine engines. These codes are usually next to the casting date code and casting number code. There are three codes I am aware of: CWC; A1, A-1 or AI; and HH. What code is on your block? What brand, year, type and size is your engine? Is the engine from a US or Canadian made vehicle? Do you know definitely what foundry poured your block?
