Re: question about c10 axle with 4.10

I think I am going to go with 3.08
That is what factory gearing would have been on early 70's mild performance cars with muncie m20 and mild v8 performance. Usually the 6cyls or autos got the 2.73..
I need something I can drive.. So I won't be able to chirp 3rd gear anymore, big deal. Ripping burnouts around town gets old pretty fast.
I priced out tbd whole thing and for a 3 series eaton posi, Richmond 3.08 gears & a Richmond master install kit, i'm looking a $770 to my door from summit. I assume I will end up paying another $400 for the install from a quality reputable shop.
I could do a tremac 5 speed, but I'd be looking at double the cost. Not to mention I would still have a 50 year old, open rear diff out back. This way the drivetrain will be all new from front to back. And I get the eaton posi that I've wanted for some time.
