Since buying the car it has been bored to out .030 over, stroked-ported-balanced and printed, added roller rockers, aggressive cam, dual friction centerfoce clutch etc., etc..... You get the picture. Today it is 490 HP and 562 ft lbs of Torque. I run it to car shows in the Minnesota area and race it at Brainered International Speedway during Wednesday night open drags. Runs in the high 12's. I drive it as much as I can!
