Description

The all new SP383 offers Big Block performance with a Small Block price tag.

Chevrolet Performance starts with the legendary Fast Burn cylinder heads and the 383cid bottom end, to offer an incredible 445 ft. lbs. of torque @ 4600 rpm with a smooth, linear delivery. The combination of a 3.800 steel crank and a stout .509/.528 lift hydraulic roller camshaft produces 435hp @ 5600 rpm, making the SP383 the benchmark by which all other 383cid small blocks will be measured.

GM's testing was completed using a GM single-plane intake manifold, a 750cfm Demon mechanical secondary carb, and 1-3/4 primary x 33 length headers with a 4 collector. A dual-plane intake manifold can be used, but will affect overall peak performance numbers by 15-20 HP.
