I've got a matching #s '66 that I have a question about. The block stamping suffix is EDH. I know ED is for the 396/325 motor with manual tranny which mine has, but the H after it is a mystery to me. Anyone seen this before? Block casting is 3855961, correct for '66. More details about this truck at http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=4534833391

I think the H stands for HAPPY to have bought that truck for that price----I will give you your money back anytime, congradulations on a heck of a bargain.... Seriously I do not know what the H stands for but I will get busy looking................................Dan
