You might want to look at this - its about 'vettes rather than Camaros but the conclusions apply to any car type.

I did it on my 79 Camaro and I LOVE IT. Despite the fact, I don't have over drive it sucks on the highway.

 

i like my 3.42's...a good in between from 3.08's to 3.73's...highway driving is very nice too

 

I have a pinion depth setting tool if you want it.
