Dave,

I honestly cannot remember but Charles knew I had projected desire for 600 hp. I plan to stroke an LSX block to 427 cu in and run the LS3 rectangular port heads. Surprisingly the Championship quick change rear wasnt but $200 more than the 9" and Charles suggested asphalt circle track cars with up to 900 hp were using them. I imagine the difference (why you wouldn't want them in a drag car) is because their already under power where a drag car is dealing hard launches in the first 60'? Call Charles up. He's a really nice fella. The price he quoted was for the 9" on page 17 of their catalog (available online) in as cast finish, powder coat black (additional $71), polished and machined ( additional $120) , complete hub to hub with center section and their trac posi less axles. The 31 spline axles additional $375. Man that is not a bad price for a rear that looks that nice. I was and still am really impressed. I've been putting off calling them for two years because I really figured they were much higher.

I keep looking at the aluminum center with the black paint in their website, don't necessarily like the black, but with the aluminum smoothed a bit and powder coated a nice color might be just the ticket under my '57......
