You arent gonna save anything on the bottom end from what I see if you are putting good aftermarket parts in it. The BIG at least in my eyes benefit is the valvetrain. It appears I can make the same horsepower and the valvetrain will live forever verus this roller cam that I have now that beats up springs, lifters, pushrods etc. Its gonna cost you $10,000 on the engine to go well in the 9's like I am with a small block at 3000 lbs. Its gonna cost you about the same with the Gen III if you are switching everything over including headers and the ignition but the Gen III appears as though it will live longer. At least thats what I am hoping for. The ongoing maintenance is where this will pay off. MLS head gaskets $45, cheap springs, etc.
