I just rebuilt a 360, .40 over, edlebrock intank, 670 truck avenger carb, summit RV cam and everything else stock. We estimate it at 350+lbs of trq. It's mated to a fresh ax-15 and I know other guys that have run a stock 4.0L clutch with no problems, but my slips real easy.

I originally had 3.07 gears and 35's after the swap and could bearly drive the damn thing because it slipped so easy. So we grab a set of a 4.10 axles and swapped them in and it's much better but in 4th or 5th gear and accelration more than gentle causes slipping and medium hard acceleration in any of the first three gears will make it slip.

I looked at the centerforce dual friction which is rated at about 300lbs of trq but I don't feel real confident that it will be enough and after a dozen times pulling the trans out I'm getting pretty frustrated.

So what are my options for a clutch? Please, any advice would be great, I'm getting desperate.
