Found the issue, stupid me I was measuring the transmission angle using the pan.. turns out the pan and valve body are not parallel to output shaft.. by 6 degrees. The actual angle, measured at the rear pad, was nose up by 1 degree. With the rake of the car, that is exactly what is normal. With this revelation, my driveline angles are all correct. 2 degrees of wrap-up brings me to parallel.
To address the earlier naysay asking why I have Caltracs on a street car (Why do any of us have any of the power or performance adders we have on street cars) consider this. I can stomp on the gas from a standstill and accelerate under full power, perfectly straight, with my hands off the steering wheel. The #3700 car has a mild 360, 3.23 sure grip with 28" tall tires and does a 6.2 second 0-60 (no launch, just mashing gas in D) consistently, every time. Just hooks, and goes straight. High speed turns, such as freeway on-ramps, are rock solid with minimal body roll. This is 100% due to to the suspension setup. You don't have to drag race to appreciate improved handling.
