JPC Racing’s engine builder of choice is Rich Groh of RGR fame. Rich knows how to make horsepower, and Bryan’s GT boasts 630 of ‘em. The ProCharger D-1SC has a lot to do with that number, but all is not lost in the preparation for that kind of power. Rich started with a Dart Sportsman block and filled it with a Scat crank, Eagle H-beam rods, custom CP pistons, and an Anderson Ford Motorsport B-451 hydraulic-roller cam. Rich also worked over the combo’s AFR 185 heads before JPC bolted them down, along with the Edelbrock Performer RPM intake. Fluid containment is left up to Cometic head gaskets, a Canton Racing oil pan and aluminum valve covers, and a Fluidyne radiator. The ProCharger ingests air via an Anderson Ford Motorsport Power Pipe, a Pro-M 80mm mass air meter, and an Accufab 75mm throttle body.
