OK, I went and bought and inspection camera/borescope at Costco. Quite a deal I think at $150. It takes video and pictures and came with everything to operate. Fun toy!

Anyway, the piston number is 3963551 which comes up as 12.25:1, first used in the 1970 LS-7 engine.

From GM Parts Direct Website:

3976014 High Performance Piston
This 454 standard, pressed pin, high performance piston has a 12.25:1 compression ratio and an open dome. (ID#3963551 or 3976032). Used in engine assemply P/N 3965774.

Thanks,

Jason
