Hi Guys,
Just picked up a '61 Biscayne over the weekend. It was originally a 6 cyl car, but now has a W engine. I was told it was a truck 409, but I think it's a 348. It has a 409 oil pan with passenger side dipstick. Casting #3857655 which I believe is 348 truck. The stamp on the front pad reads: T0603XB. Anyone seen this suffix code before? Thanks for your help.
