I'm really enjoying my truck but have had an ongoing drive line noise/vibration problem that may be related to a u-joint angle problem. I installed a camero 5 speed behind a 261. I left the long tail shaft on because I had the room. I shortened the front driveshaft but all this changed the angle from the carrier bearing to the trans. tailshaft. I installed two wedges between the carrier bearing and the frame member it is mounted on but I think I need more correction.
Here is the question: if I raised the front of the engine by adding a spacer to the engine mount would I hurt the running of the engine?(oil pump, or...) Is there an easier way to corrcet tha angle that I am missing? Thanks, Don.

You won't be able to raise the engine by much before you cream the radiator with the fan. So it won't hurt the engine, but the rad may not like it. But you should be able to do something else with the driveshaft.

Are the two piece drive shafts installed correctly? That is the center u-joint should be 90 degrees out of phase with the two end joints.

Thanks for the ideas. The radiator thing was pretty obvious after just a little thought!
Here is how I solved this problem: I cut 3/4in. off of the carrier bearing "carrier" which raised the front driveshaft a lot and only changed the angle of the rear shaft a little, resulting an almost lined up pair of shafts and the noise and vibration are gone.
