Big boggers need big power, and Rick's Chevy 454 big-block, bored 0.030 over and running 13.0:1 compression, is built to deliver. The balanced block is stuffed with SRP forged pistons and a solid .632-inch-lift roller cam. A Team G intake manifold works with the Holley carb to feed fuel through the runners, and 1 7/8-inch Hedman headers funnel exhaust gases to 3-inch Flowmasters-and in case that's not enough grunt, a 150hp NOS nitrous system is plumbed into the intake. Dual Optima Yellow-Tops provide the juice, and a Mallory Hi Fire ignition and coil, MSD distributor and wires, and an owner-fabbed wiring harness work to regulate and flow the volts. On the bottle, Rick estimates his big-block is good for 675 hp and 690 lb-ft of torque.
