Get ahold of Cass @ Dr. Diff. He will get you set up with everything you need.
I missed the part about your motor having +600 HP and slicks. I would highly advise moving up to a 9 as well as a housing that will allow for a larger/stronger axle. The reason I say this is my car has a built 340 with nowhere near the HP of yours and I found out that the stock axles where twisted. Randy's set me up with an axle that was 25% stronger than stock but I doubt it would be able to handle the load of your HP plus slicks. Randy's is very well known for their rear end setups. They are also owned under the same ownership group as Yukon Gear. Just an FYI so you have some choices.Ok so I talked to cass, he says I may be pushing the strength limit of the 8.75 Chrysler. Last thing I want is a weak spot in my set up. Now I asked him what he would recommend using other than the 8.75, while waiting a response from him i wanted your guys opinions on a 9" axle housing set up, was looking at a set from Reilly motorsports since it would bolt right up to my street lynx 4 link. Can anyone share opinions on the 9", stregnth compared to 8.75. Anyone with any input I would appreciate your insight.

Thanks buddy, i appreciate it. seems the concensus is move up to a 9" is the best bet, I've created a for sale thread for my 8.75 if anyones interested, check it out.I missed the part about your motor having +600 HP and slicks.
