I have a 69 camaro with a ZZZ 350 (345 hp) and a 700r4. The tires are 25 inches tall. I'm building a 12 bolt with posi. It is my daily driver but drive mostly in town and not much highway. I want to be able to race it. I'm thinking of getting 3.55 or 3.73 gears. What kind of rpm's will I have running at 60 and 70 with the 3.73. What should I get? Thanks

I'd say go with the 3.73 since you have the overdrive. That will net you about 2300rpm at 65mph with a 25'' tire.
