Default Re: Mopar 8 3/4 users question for ya

I've got one in my S/G car, but it has pro gears (the special 4.75 ratio ones). When I bought the rolling chassis it had 4.89 pro gears, and they lasted a couple of seasons on the trans brake (around 1.32 60' times, car weighed around 2500). After they broke I ended up using "street" gears, and they would last about 300 passes or so before breaking. I think I broke 3 sets, and no two sets broke the same way. Nowadays the car runs 1.29-1.30 60' times, weighs about 2400, and has been working well with the 4.75's in it.

Regards,
