UMP Dirt Car Series Sportsman

The Learning Curve is a 1980 Chevrolet Malibu that has been modified for drag racing. The name "Learning Curve" was developed when the car was first built because learning takes place every time the car is worked on or raced. The car is run most often at Coles County Speedway, an 1/8th mile track near Charleston, IL.

A 355 cid small block Chevy with Edelbrock E-TEC 200 heads and a solid lifter Bullet camshaft power the car. The Holley 4150HP series 750 cfm double pumper receives fuel through a Holley Blue pump and regulator. An MSD 6AL ignition box and wires help light the nearly 13:1 compression ratio provided by SRP Pistons. Dyers billet steel connecting rods add durability to the balanced rotating assembly. A Precision Industries converter and TH400 transmission with a TCI transbrake multiplies torque. More than 540 horsepower is transferred to the rear wheels through a Moser prepared 9-inch rear axle with 4.88 gears and a spool. The rear axle is held in place by a set of double adjustable Art Morrison Ladder Bars. 29x9x15-inch Hoosier drag slicks put the power to the track, while Wilwood Disc brakes help stop the car at the other end.
