Pinion angle help
Hello I have a 71 nova ,sbc 625 hp, I've changed over everything in the drivetrain, Trans=PG, Drive line= 3.5"DOM W/1350 joints, Chris alstons 9", Cal Tracs split leafs and Cal Trac bars, 10.5" MT slicks. to set up the pinion angle I measured the crank shaft/trans center line angle and the pinion angle with the driver in the car and the weight of the car on the tires. I found them to be within 1/2 degree of parrallel of each other ( the half degree was negative or down at the pinion ) the drive line working angle is 5 degrees. I've installed 4 degree pinion wedges to get more negative pinion angle which puts the pinion angle at about 4 1/2 degrees negative. With the drive line working angle at 5 degrees and the pinion angle at 4 1/2 degrees negative with respect to the trans center line angle it put the rear u joint angle total at 9 1/2 degrees static. Does this sound correct?
