Hi can anyone tell me what the castor angle on a 73 camaro should be standard from the factory.
Thanks ASH

 

I'm not sure about 73, but in 79 the specs are +0.6 camber and 1.0 caster. With that said, I will tell you from experience, these settings drive like ****. You want it to drive like it's on a rail? use these specs: -0.2 camber and 2.0 caster on the left side and 2.2 to2.3 caster on the right. You can angle bore the holes in the upper arm to allow more adjustment. the most caster I could get was 1.9 deg. on the left without drilling the holes, it all depends on the car, everyone is different. Remember, the key is the -0.2 camber and 0.2 to 0.3 stagger on caster. I bet you could float between 1.5 and 2.0 caster and it would work.
