Got a GM pickup with a tired, sick, or broken engine? Chevrolet Performance has exactly what you need. Their 350 c.i.d. truck long block assemblies are built up from 1987 and up style 4-bolt main blocks with one-piece rear main seals. To this, Chevrolet adds a nodular-iron crankshaft, powdered-metal connecting rods, and hypereutectic aluminum pistons. You also get power-producing cylinder heads with 1.94 in. intake valves and 1.50 in. exhausts, and 76cc combustion chambers that yield a gas-pump friendly 8.75:1 compression ratio. This combination is paired up with a hydraulic cam that has 0.382 in. of intake lift and 0.402 in. for the exhausts. Duration at 0.050 in. of lift is 165.9 degrees for the intakes and 174.8 for the exhausts, with 111.9 degrees of lobe separation. These engines come complete with an oil pan, timing cover, valve covers, and harmonic balancer.
