Need a Clutch

[Valair1]

Well found out that standards arent made to do burnouts and in the process in burnt my clutch pretty good. Now i'm researching a new performace clutch and would like to know what clutch would be good for a stock truck that will be going to be around 500 to 600 HP. I've looked into Spec, South Bend and Valair, and it seems that the prices go in that order also. Is there really much of a difference between the 3 brands? Money is pretty tight right now so i'm leaning away from a double disk.

to get this thread back on track, to the original poster, honestly 5-600 hp that isnt even close to stock, boosted launches and or aggressive driving, no single will hold. and if it does it wont be too streetable, save for a dual disc. Our clutches are rated first engaged and torqued unitl they slip, then we back the rating off and set it, not spun wide open or building boost then launching,JMO
