harmonic dampner i have a harmonic dampner bought from gm originaly, the part number is 12498008, the question is the LT1 has a hub that the balancer bolts onto.... this dampner has a cast in hub with a keyway broached in and an external weight that bolts on. its for a 383 but it is not like a SB1 dampner for a 400 crank, and im not sure what its for, LT1 or ?. any help would be great
