Big Block SuperCharged Chevy Engine Dyno Testing

This engine was tested before with over 730HP using steel heads and Predator Carbs. This engine will be going into a prostreet 1969 Camaro and has been refitted with date correct aluminum heads and holley 750 carbs. The engine still produced over 700 horsepower with the new carbs and a Dyers 6-71 Supercharger. To add longevity and street-able control we swapped the pulleys and lowered the boost using 93 octane pump gas. The engine produces 652 HP and 633 lbs. of torque in this video and we are not finished tuning.
***Update 2013 - Final dyno tuning was 720 HP and 724 Lbs. Torque with pulley change.
(Please forgive the audio as it peaks a few times during the high revs - high noise level)
