Description: One strong small-block. World Products knows how to build powerhouse Chevrolet small blocks. Take, for example, their muscular 460 HP, 415 c.i.d. Motown crate engines, which put out 440 ft.-lbs. of torque. They're built around the company's rugged, 4-bolt-main Motown cast-iron block, plus an Eagle 4340 forged-steel crankshaft, 4340 forged-steel H-beam connecting rods, and 9.5:1 forged-aluminum pistons with performance rings.

Description: One strong small-block. World Products knows how to build powerhouse Chevrolet small blocks. Take, for example, their muscular 460 HP, 415 c.i.d. Motown crate engines, which put out 440 ft.-lbs. of torque. They're built around the company's rugged, 4-bolt-main Motown cast-iron block, plus an Eagle 4340 forged-steel crankshaft, 4340 forged-steel H-beam connecting rods, and 9.5:1 forged-aluminum pistons with performance rings. The cylinder heads are World's own Motown 220 cast iron units, fitted with Manley Racemaster stainless steel valves (2.080 in. intake, 1.60 in. exhaust), aluminum roller rocker arms, and chromemoly pushrods. The cam is a high-performance hydraulic type. In the induction department, World picked one of their Motown aluminum intake manifolds, topped off with a modified 870 cfm Holley 4-barrel. For the ignition system, they chose an HEI distributor, and 8mm plug wires. These Motown engines are internally balanced and are fitted with a Hardcore CNC-machined harmonic balancer. They're assembled with Clevite bearings and quality components from Fel-Pro, ARP, and Manley, and they come complete with Motown valve covers. Each engine is individually dyno-tested and certified to meet the advertised power output. (minimize)
