I'm kinda new to the whole, 'Real-horsepower and SS-owning' thing. I am getting a little whine from my rear end. I think it needs lube, but it got me thinking about getting a better one. I am pretty sure it is the 3.42 with posi. With the few mods listed below, and possibly a supercharger in my future (couple years) what would be my best bet for laying down most of the horsepower?


Thanks,

John

 

same thing happened to me. my pinion bearings were shot.

 

If you are going to turn up the wick with a 6 speed car I would start looking at 9" or 12 bolts...6 speed cars are hard on rears and there is not much you can do to make 7.5" ring gear last under a lot of power and hard launches. The girdles, bearing studs and solid spacers help, but when you're all done you'll still have a weak ring gear, and that's whats going to break...
