68 Barracuda Fastback build

My friend showed me this build. Overall it's freaking sweet, but 7700rpm with stock pistons, rods and crank has me wanting to know the rest because if so that's a build I'd like to replicate.
stock crank and rods, all blueprinted and balanced with KB hypereutectic domed pistons. Theoretically, it could rev to 8k and above but the torque and power curves don't really improve at higher RPMs so no real gain with lots of potential failures...
