Greetings all,

With my new engine and T56 transmission I figure it's time to upgrade the rear end.

I spoke with Joe at Strange Engineering, he recommended that I stick with my stock rear end and upgrade to Strange axles (30 spline) along with a new Eaton Posi. He said that setup would be fine for 400-700 hp.
Sticking with the stock rear allows me to keep the new Baer setup I just installed. This is about where I want to be with my final drive: Max RPM 6000, Tire Dia. 27" MPH: 140

Can I get some reccomendations?

Hmmmm, just what 'stock rearend' do you have now and what type of car is it in?

I have a 12 bolt Posi. It orginally came out of a 69 BB car.
