Bought a 67' camaro rs recently and seller listed as a 350 small block. Obviously not an orginal motor.
Looked up the stamps on the block.
Casting number is 3932388 which would be a 69' 350 small block.
However, right front block is marked as T0522HV which should be a 327 small block 1965 corvette engine produced in Tonawanda.
Anybody have a clue what I have here?

Thanks

 

According to the "Lime Book" shown below, the HV designation was used twice on a small block Chevy. Once in 1965 for a 327 CI/350 HP Corvette and again in 1969 for a 350 CI/255 HP Full Size Chevy Passenger Car. I don't know if both engines used the same block casting number, but checking the casting date will eliminate one.

 

Thank you. Big help, I hope it is the 327 vette motor. Will look for date casting.

 

The partial VIN on the block will also give clues as to what car it was originally installed in. The model year and assembly plant are the second and third digits, I think. I did check later last night and the two engines used different block casting numbers. The block you list was used in 1968 - 1974 Camaro, Chevelle, Monte Carlo, Nova and Passenger. It was also used for 1969 - 1976 trucks. The 327/350 horse Corvette engine should have been a casting number 3782870 if I'm reading the chart correctly.

 

Thank you peterpar.
I was looking at other information on the web today and it appears that almost 100% of the 1965 vette 327 blocks were made in flint Michigan. Tonawanda, however would sometimes support Flint. Being that and HV was produced in 1965, and with my casting numbers, I'm pretty sure it a 1969 350. Car is immaculate other than non matching motor. Painted Marina Blue which I used as my handle here. Lol....
