Don't look in here.

[68400BIRD]

AAAGGGHHH!!!

I figured that if I put pinion angle in the title know one would look.

I need help checking to see if my readings are on so I can weld my perches on. I have been to every website that I can find on google searches and keep coming up with different answers. I will give as much info as I can think of.

1968 Firebird
400 motor, 400 trans, new stock rubber mounts on both.
Stock driveshaft
QA1 coil over shocks up front, Speed Tech control arms
New rear leafs with all new bushings (all bolts just snug) no binding
QA1 shocks for the rear. Not purchased yet.
The car is not complete but needs about an even amount of weight added to the front and back.
300-350 HP motor.Will only be street driven with maybe a short road course now and then.

I bought a 1968 Camaro 12 bolt rearend that was in a friends 41 coupe. I had to cut off the perches that he was using and tack some correct ones on to put it in the car. I think I have it close but the more that I read on the internet the more confused I am. According to Currie I think I did it correct.

I will base everything off of 0 degrees to make it easier.

I first started with leveling the car the best that I could. My garage floor is horrible.



I started with my reading off of the tail shaft which should be the same as the crank. 4 degrees down. Factory should be 3 degrees down, but my leveling could be off one degree.


Pinion angle 3-4 degrees down. I have read that you do not want the pinion ever pointed up.



Drivesahft angle is 2.5 degrees up.

According to Currie you want less than 2 degrees difference from drivesahft to trans shaft and driveshaft to pinion.

So,I would have 1.5 degrees down on the drivesaft to trans output shaft and 1-1.5 degrees down on pinion shaft to driveshaft.

Does this look correct?????
