In the dragster?
Basically changing the height of the center of gravity/mass?

If the crankshaft centerline is 1.5 degrees up, the output shaft is down 1.5 degrees. Which would mean the pinion would be up .50 to .75 degrees, to arrive at or around 1.50 up degrees under power.

After the crank was moved 0 degrees, the output was 0 degrees also and the pinion down .50 to .75 degrees, to arrive at or around 0 degrees under power, at the hit correct?

Less up pinion angle allowed you to better tailor the driveshaft graph correct?

Solid dragster better be crank shaft aligned pinion. As in the face of rear housing parallel to the motor plate. Keeps em outta the cones.

I a word, no.

I am talking about a hardtail car here, so the pinion angle does not change under power. Didn't change the pinion angle, just the engine angle relative to the frame rails.

Just the rear, since the front of the engine was going lower they were able to use the front one over.....

Bender have you ever seen a hardtail with adjustable height saddle mounts ? Pretty cool ....

They are just like regular saddle except the "tab" that the motor plate bolts to is on a jack screw affair to raise and lower the "tab" to raise and lower the front of the motor to take bite away or add it.
Super popular on the comp eliminator hard tail dragsters.
Spitzer has built a bunch of them.
Hell we run our comp car -1.5 down in the front to try to take the wheel stands away
