'67 Camaro E/SA redo

HandOverFist · 04-24-2014, 11:36 AM

Just got confirmation this morning that the 200 case was cracked as well. Even with all the components being replaced on this car I want to get as many eyes on it as I can before it goes back out. The builder of the new drive shaft reports that the old shaft was just slightly out of balance...I'm thinking it had little to do with our problems.

The following parts have been checked and/or will be replaced -

New drive shaft w/1350 yokes

New tubular transmission crossmember (will stick with the poly mount)

New solid motor mounts (both being equal height)

Sub-frame bushings checked for tightness

My best guess is the mis-matched motor mounts were the primary cause of most of the woes we have experienced...have yet to come up with a logical reason for someone doing that. I believe the original slapper bar traction device masked/cushioned the problem. With the introduction of the Caltrac's and the subsequent higher shock loads things began to fail. With everything in it's proper place and working together I predict some low 1.40's in 60' times. Btw, the torque convertor appears to be unscathed.
