PERFORMANCE ENGINES & TRANSMISSIONS JASPER Engines has four levels of engine performance for your project vehicle. "Stock" is the general production engine offered in a production vehicle.
Stock engines receive JASPER's tried and true methods of remanufacturing, including torque plate honing, three-angle valve seat machining Precision crankshaft machining, oil chamfering and polishing and computer-assisted live-run testing.
The "Class I" engine is the same JASPER general production engine, but with a mild camshaft upgrade. Class I engines generally produce about 10% more horsepower and torque over the standard stock engine.
