Previously posted about distributor help but now need additional thoughts on the engine vibration. Car has a vibration in neutral with clutch in or out, and also when driving. Seems to come in at 2000 rpm and up. Seems to be getting worse. Was told that crank thrust bearing may be worn as end play is slightly more than is recommended. Never vibrated with original 3 speed, now has T-5. Also, same time I switched trans, I also put a blue thunder intake and edelbrock 600cfm carb on the car. Can the thrust bearing be causing the vibration? Or is it something to do with the carb set up? Already changed the balancer to rule that out. Car runs great up to around 2000 rpm. Engine does not have a miss (already went through the plugs, wires, distributor, and coil). Anything I am missing? Thanks!
