Through some "horse trading" I ened up with a '95 LT1 long block. My '62 Impala needs an engine so...I would like to convert the engine to a carb and HEI distributor. I plan on using a GMPP intake and opti spark delete plate. I need help on locating a keyed balancer with timing marks that would use the stock serpentine accessory drive belt. I would prefer to use a GM balancer as opposed to after market. Can anyone help? Has anyone performed this conversion?

 

There is no GM LT balancer with timing marks.

Powerbond has one, Fluidampir and ATI

 

And if I may, I'd like to save you the trouble of a search.

The majority opinion seems to be in favor of ATI, although Fluidamper has it's advocates under 6500 rpm.

 

I have an ATI superdamper, it has 360* of timing marks and is keyed.
