Jared Gastineau and his company Mile High Muscle<\/a> invested many hours building this amazing 1969 Chevelle. The classic A-body is powered by a 10.3 L ZZ632 V8<\/a> crate motor capable of 1004 hp (738 kW) and 876 lb-ft (1187 Nm) of torque on 93 octane fuel and 12:1 compression.<\/p>\n

The motor features an iron block with a forged 4340 steel crank, forged steel H-beam rods, and forged aluminum pistons. On top of the motor are aluminum spread-port RS-X design heads with an aluminum high-rise single-plane intake manifold.<\/p>\n

Behind the motor is a McLeod RXT 1200 twin-disc clutch and Tremec TKO-600 five-speed manual transmission. A QA1 Rev Series carbon fiber driveshaft transmits power to a Dutchman 9-inch rear end. Inside that is a Strange nodular center section, Eaton TrueTrac limited-slip differential, and 35-spline axles.<\/p>\n

Jared tossed the factory chassis for a Speedtech Performance ExtReme chassis<\/a> with their forged aluminum spindles and torque arm rear suspension. Road bumps are handled by JRI single adjustable coilovers. The brakes are Wilwood Aero six-piston calipers with 15-inch rotors in front and Wilwood Aero four-piston calipers with 13-inch rotors in back. Those are covered by a set of Schott Mod 4 EXL wheels (18×8, 18×12) wearing Nitto NT555 tires (235\/40, 335\/30). <\/p>\n
