Under the hood lurks a potent 454ci V-8 engine that spawns 540 hp at 5,700 rpm and 590 lb-ft of torque at 3,300 rpm. The folks at West Coast Cylinder Head completed all of the machine work. The powerplant features a laundry list of power-producing components, including TRW forged pistons with polished rods and ARP bolts; ported and polished cylinder heads from a 427ci truck engine; Melling oil pump; 7-quart oil pan; Competition Cams camshaft and double roller timing chain; Crane roller rockers; Edelbrock Performer intake manifold; Mickey Thompson valve covers; 850-cfm Holley carburetor; K&N air filter; Doug Thorley headers; Flowmaster mufflers; 2.5-inch-diameter exhaust pipes; and an MSD distributor, coil, ignition, and wires. Here you can also see the custom bolt-in engine cage that mounts directly to the Blazer's frame. It serves as a mounting point for the front King coilover shocks. The engine is bolted to a modified Turbo 400 automatic transmission that features a slew of modifications including an Art Carr pan and shifter.
