This corvette is spoiled kept in the garage under the car cover I never drive it in the rain or below 45 degrees. Have another set of wheels and tires. I put on a high flow filter, installed a Tony Mamo ported throttle body (more throttle response mainly), Corsa X-Pipe with new Corsa Extreme exhaust, and had it tuned here in Norman by Deep Stage Tuning. It was put on dyno and had 420 to the wheels. It’s estimated that you lose 20% from crank to wheels so that would mean an estimate of 504 HP at the crank
460 I think was factory HP at crank. Call me or text me if you have any questions.
