.Vibration
just built my 347 up and dropped it in. started it up and held it at about 1800 rpm for 10 minutes. after that i reved a couple times id say between 6-8k everything seemed fine. I took her out on the road takin it easy shifting about 4k. so heres the problem..... around 4k it wants to vibrate quite a bit, Im thinking it may be my harmonic balancer(it looked a lil messed up). I talked to the guys I had balance averything and it was balanced to the 28oz harmonic and stock flywheel so all thats good. has anyone had this vibration after a build up?

WHOA.. wait a second......
this cant be right, Your car takes a 50oz imbalnce both front and rear, not 28oz front and 50oz rear... something tells me they screwed up. If your using your stock balancer, your not using a 28oz, but a 50oz... which they claimed to have used a 28oz
