[Chevelle-List] small block id

[KNUTSONChevelle]

Hey does anyone know what year model this 350 is?
The id on the front pad of block is V1102TKY.
I want to replace the hormonic balancer & want to get the correct one.  I have a bad vibration problem going down the interstate. Already had the driveshaft balance & I see the rubber poochen out of the hormonic balancer, so thought Ide try that route.
Any advice on what hormonic bal to get? Its just a street week end car.
Thanks for your help
Dan
