Al Papitto at Boss 330 Racing built the 283ci Four-Valve with a Cobra crank, Manley rods, and CP forged pistons with Mahle piston rings. Al also treated the B-heads to a valve job, stainless steel valves, and Crower Stage 2 camshafts to match the company's valve springs. The Cobra intake received porting, shortened runners, and an Accufab throttle body. All-important billet oil-pump gears make sure everything is well lubricated. The focus on lubrication is due to a couple of things. First, the Four-Valve engine likes to rev. Second, the ProCharger F-1R just fore of the passenger-side cam cover is capable of forcing 23 pounds of boost down the Four-Valve's throat. The stealth exterior gives way to a ferocious symphony of supercharged power when this thing is running. The sound belies the 9.80s Andy's Cobra blasts at Orlando Speedworld Dragway.
