My mechanic/machinist/wrench is asking me questions about the clutch as he is finishing the super charger install. He wants to know how much the stock clutch will handle with just heavy duty springs. At what point do the plates need other attention? We are not sure what the hp will be being there are different cams and Carpenter header. Warp?
 
stock clutch with uprated springs will be fine
But if in doubt fit MTC plates, 400hp 300ftlb & no slip

I agree with Les on this.

I hope the install goes well make sure you add fuel to the base tune to start with its better to start out rich and back it down then to start out lean.
 
Thanks guys. Great help.

Nev, still running your cams. They, with the Jardines, triple KNs and a Power Tripp tune have been working quite well. Of course an extra free 20hp? No reason to leave them unharnessed. I or Mugzy (aka Chopper Jon) will be in touch. Thanks tons Nev. You 'da man!
