LSJ Rods - (less than 300 HP only)
LSJ Pistons - (less than 300 HP only)
LSJ Rods are made out of high quality forged steel
In the 400-600 HP range, they recommend upgrading your valvetrain

Pistons = 300??? (i'm at 330 now so we will see)
Rods = 500+
Crank = 700+
Block = 700+
Fuel system = 400??
Cams = 400
Valvtrain = 6800 rpm continuous ( haven't determined the timeline) I have hit 7600 for a split second though!
Cylinderheads = (thats my secret! Got to keep an edge over the competition some where!)
Intercooler = Depends on MANY variables to nail down a number!
Tranny = not sure
Axles = 1.90+ 60's and less then 2500rpm launch, Broke stock ones already, testing new HD ones now
My souce can not be divulged but it is reliable
