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 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?
