Well I did a 347 motor swap and an aode to 3550 tremec swap (using the auto driveshaft) at the same time but now theres a problem, the car shakes pretty badly. It vibrates alot when RPM is climbing. I don't think its not the balancer that is bad because its only has 3k miles on it and it seem fine. The stock motor mounts are new so I dont think thats it. When we was putting in the Tremec we didnt have enough bolts for the bellhousing because we use the auto bolts---> (doesn't fit fully) and also one bolt was missing from the Tremec to the bell. Could the missing bolts be the problem? Does it matter if I use an automatic driveshaft?
