As posted previously; forget power, focus on suspension, brakes and tires. A tune will liven the engine up. A BAMA 91 race tune is all that is needed.
Start with a new rear upper control arm to stop the wheel hop, and then go from there. Springs, shocks, roll bars, bushings, brakes, Watts link, etc., etc.
