Re: engine decode

The first number is a partial VIN. The second isn't making a lot of sense. Atr you sure its clear? The T would indicate that it was built in Tonawanda. You can find the casting number on the back, drivers side of the block just behind the cylinder head. The date code is back there too.

Re: engine decode

Putting those numbers with the casting and date marks off the back of the block would help more, because the numbers here dont entirely make sense, but I'm thinking this is likely a 275hp 350 built 11/15/68 for a 69 chevelle, nova, or camaro. Maybe pull a valve cover and check the head casting numbers to really nail it down.
