Chevrolet Performance 19435440 - SP350 Base Crate Engine - 385HP

You can achieve modern street performance in classic small block form using one of these Chevrolet Performance SP350 385hp base engine assemblies. They produce 405 ft.-lbs. of torque at only 3,600 rpm for a amazing back into the seat push of performance. The engine assemblies feature aluminum cylinder heads based on the proven Fast Burn design with large intake runners and 2.000 inch diameter intake and 1.550 inch exhaust valves. The new beehive-style valve springs achieve greater high-rpm performance and longevity as the egg-shaped springs have less reciprocating mass in motion, needing less spring pressure for greater valve control, and maintain valve-train stresses more efficiently. It is also backed by a 24 month 50,000 mile limited warranty.
