How's this for tuning!
703 rwhp on a Corvette!
Ed had the opportunity to fly out to California and tune on a LT4 383 with a Vortech blower running a modest 16 lbs of boost. The engine was built by Nelson Racing Engines.
Ed said that you can't even tell that it has that much power just sitting there idling.
Quote "It idles dead smooth at 800 RPM, drove like a stocker until about 3/4 throttle. :)"
