3.07 and 3073 are most common.
What engine, trans?
Anything unusual about it?

Running turbo 350 Tranny and standard 350 V8 engine. Nothing special in performamce dept. My thoughts were 342 or 373
We want to go to a 2004R Ttanny without changing the gear.

I used a 2004r in my '69 Suburban with a 3.73 and it worked great. The burb had a 3.08 in it when I got it and that wasn't satisfactory with the 2004r.....
