Hey, Nice lookin 40. What about that 350-why a mystery? Welcome to the life. Is this your 1st 40?
So previous owner said it was from a 72 vette. The only numbers I could find on the rear of the block are:
3970010
m47
871 888
13434N
When i look up the first number I find:
Years - Casting - CID - Low Power - High Power - Main Caps - Comments
1969-79 3970010 350 185 370 2 or 4 car, truck, Vette
sooo basically it could be a truck or vette or car.. hah
When I replaced the clutch it took one with 10 teeth. Apparently 72 corvettes clutches have 26 teeth.
