Single Disk Southbend Vs. Valair
I had a few questions regarding my options in buying a new clutch. I am swapping a 96 cummins and a nv4500 into my '88 GMC v3500. Upon inspection of my stock flywheel I noticed several cracks on the contact surface of where the disc rides. So I definitely need a new flywheel. I had a #10 fuel plate, afc tuning, and timing bumped a little in the dodge and had enough power I slipped the clutch a couple times so there is also mild heat damage to the flywheel and disc. I want to upgrade to THE Valair #NMU70279-01-5SCE, its the 13" flywheel and organic clutch kit. Most sites I look that sell this clutch kit claim 400hp and 900ft lb holding capability such as here>>> http://www.thoroughbreddiesel.com/va...79-01-5SCE.htm. But the Valair website only claims 350hp and 800ft lbs capability. My motor is balanced, rebuilt .40 over, tuned, and will push 36psi boost, I think with more fuel I will be on the up side of 350 hp. Will the Valair clutch hold the power? This is just a hunting, off roading, work on the farm, play around, tow the horses once in a while truck. Nothing serious. If I am going to spend the money I just want to do it right the first time thats all.
I am also considering the Southbend 13125-OK >> http://www.thoroughbreddiesel.com/so...d/13125-OK.htm.
Im not loyal to either company. But the Valair is $652, and the Southbend is $727.
So what do ya'll recommend?

yea I really had no money for a dual disc and I really did not need it. I just bought the 400hp South Bend Single Disc organic. I had $20 summit bucks so it only ended up costing me $707 shipped. It was only fifty bucks more than the Valair and I still don't know how much hp their clutch was rated for.
