I am shooting to start at 500 rwhp with my build, it has a new block, rods, pistons, ARP stuff, a form of sheet metal intake, perhaps with stock base, Jenvey base or complete custom base (waiting on that info), for the valve train we are upping spring pressure, the heads flow enough for my goals. Car is also getting a built auto and Circle D convertor and will be running on E85. My turbo maxes out right at 680 hp so that should give me enough headroom to get close to 600 rear wheel when the engine is broken in.
