    GS Motor

    Just got the motor back from the Mandys GS, after 11 seasons of drag racing and 30,000 street miles figured it was about time the pull it apart and take a look. Bumped the compression a touch, a little more porting on the heads and a little more cam (still has to idle at 800rpm with 12 inches of vacuum and sound stock), still has the stock ported iron intake and exhaust manifolds and the stock 750 Q-jet.....

    And the Numbers.....485HP.....535lbs Torque, all on 93 octane BP reformulated fuel. What the Ricers won't get, made 500+lbs torque from 3250 to 4750rpm...
