shakerb said:As i understand it, the crankshaft and the block are OK to hold 1000 BHP. What about the pistons Fourcam? Are they OK to hold 1000 crank HP? If/when I decide to change the rods, I might as well have everything done to the motor that will be required to hold that kind of power (while the motor is open). I like the Manley 4340 ultralight billet I beams.
