Thanks John. I have talked to a few guys here and it seems that the concensus is that i put the 396 flywheel on. I will pull it off and get a 454 flywheel. Also I will look into the pulley also.
Thanks for your input I really appreicate it.
Sucks cause i got everything bolted up nice to. Is it a tough job to remove and replace the flywheel in the car or would it be easier to pull the motor AGAIN...LOL
Does the balancer appear to have an actual wobble for part of its rotation or is it just always that that close to the water pump that it rubs slightly?
If it actually has a wobble could the crank snout have hit anything in transit anywhere (machine shop etc) to bend it and that is causing the balancer to wobble? If other things check out keep it in mind.
Probably the balancer and /or flywheel as others have mentioned but the bent snout came to mind because a friend bent his while trying to get his motor in and didn't notice it and it sounded similar to the way his ran afterwards... Randy
