Default Strange Engine Stamping



Casting number 3903352


stamping T080IHC
I am trying to understand the origins of the 327 in my '68 that I was told was original. I suspect otherwise. The casting is a 3903352 which is a 2bolt 327. The stamping is T080IHC. That is right, only seven digits. Any Idea what this came out of? Maybe a GM crate engine? Some rare engine I could make millions on?

HC indicates a 65-68 327 passenger car engine. It is not a Corvette engine. Corvette small blocks were assembled at Flint (V).

so I feared. I know the T stands for Tonawanda. What is the "I"? Am I missing a digit from the date code?

Alpha Is were sometimes used in place of numeric 1s.

No. Date codes are two characters for month and two for day of month.
