Default Drive Line Angle

65 GTO w/68 400 and TH400
100% dedicated drag car

Engine angle is 4.5 degrees (downward) at harmonic balancer and confirmed at tailhousing shaft

Driveshaft angle is 2.8 degrees (downward)

This equates to a 1.7 degree working angle and I keep reading that the preferred angle is 0 to 0.5 degree.

Would you shim the transmission mount to reduce engine angle and get it more in line with driveshaft?

If so what thickness roughly?
