OK, first off let me admit my stupidness. I pulled the balancer off the 6.0 without marking or even looking at it. I am familiar with the LT1 how it has no keyway but has an arrow on the hub that points up, but I don't see any markings on the 6 liter balancer. Does it matter how it goes on or are these things internally balanced?

 

The balancer should be 'neutral balanced' meaning the motor is internally balanced. No timing marks or keyways to mess with.

Yes, it's not a balancer, it's a pulley.

 

OK, thanks. Now I know how to install my harmonic pulley! I was pretty sure that it didn't matter-just wanted to make sure. Probably be putting it back on tomorrow night,
