Engine Number Question
According to an article in Corvette Magazine on engine numbers, no small block engines from Tonawanda were used in Corvettes in 1964. However my engine number is 108515 T 0528SC and my VIN is 40867
S108515. Doesn't the "T" mean Tonawanda?? I know the car has been altered - because it is now a 365HP 4sp. and according to the SC suffix, it began life as a 250HP Powerglide. Strange!!

What is the block casting number?
Take a closer look at the engine number an make sure that the "T" is not a "F". If your block casting number is 3782870, the prefix should be "F". If the block number is 3858180, the prefix should be "T".

The VIN derivitive stamping should be 4108515 for 64. The T 0528 SC translates as Tonawanda, May 28, 250HP Powerglide trans.
T does mean Tonawanda, NY.
What is the casting # of your block? What is the casting date? Chuck

The plot thickens...
The block casting number is indeed 3858180 and the date stamp is E25.
Does that mean it was cast May 2nd 1965 or May 25, 1964?
If it is a '65 engine that somebody put in, how can the engine number of 108515 T 0528SC agree with the under dash VIN plate of 40867S108515? Which is a 1964 VIN? (The under dash VIN plate is surprising clean and shiny - did someone alter it?)...

Flint blocks have a single digit year, i.e., E 2 4, or E 2 5.
Something isn't ringing true here. You have a "180" block. You have a Tonawanda stamp, but you have a Flint single digit date.
I'd double check the date again.
Regardless, the date E 2 5 that you post would be May 2, 1965, WAY after the assembly date of the car. Chuck

Don't get me wrong guys, the car was never marketed to me as original or a numbers car. The dealer and I agreed the engine was replaced or re-built. It appears to be a 65 327 not originally in a Corvette.What gets me is that the engine stamp has the correct VIN derivative of 108515??

Sounds to me like it was restamped by someone who didn't know what they were doing.
Stamped a T for the plant...missed the 4 in the VIN. BUT, I still don't understand the single digit cast date. Chuck
