Tony Bischoff and Gary Rohe from Bischoff Engine Service [(812) 637-5933] helped Ricky out with a trick, little Pure Street mill. It's based on a 4.060-inch bore, '91 5.0 block, which measures out to 310.8 ci with the help of a stock crank and 10:1 Ross pistons connected to Probe rods. Brian Tooley from Total Engine Airflow ported the Trick Flow Twisted Wedge heads and stuffed them with 2.02- and 1.60-inch valves. The camshaft is a custom BES piece that specs out to 0.500 inch lift (per legal class limit) with the help of 1.5 Crane roller rockers. And, as stated in the NMRA rule book, the lifters are stock-replacement units. All totaled, there are an estimated 450 flywheel horses ready at the blip of the throttle for Ricky's enjoyment.
