Is the crank in your 383 internally balanced or externally as a SB 400 is? Running the incorrect balancer or flexplate/flywheel will cause issues.

It was internally balanced along with the flywheel, I ran into trouble when I was changing the motor from auto to 4 speed when I put in the truck. I finnally found a machine shop that match balanced the standard flywheel to the auto flywheel. How ever I did put a few miles on it with first a 350 flywheel and then a 400 flywheel before figuring it out. I completed the Hot Rod Power Tour driving my truck somewhere north of 2,300 miles in 8 days with no trouble. I hope I have these issue behind me.
