The Engine Master SB Chevy is built from a new GM Goodwrench long block. By replacing key components (heads, cam, manifold, etc) we are able to increase horsepower by 150 or more. Each engine is carefully assembled, then run in on our SuperFlow dyno to assure proper Camshaft break-in and proper ring sealing. After the 30 minute run-in, the engine will be tuned to fine best timing and carburetor jetting for most torque and horse power. After the Dyno test session the heads are retorked and valves are reset. This is truly the ultimate 'Turn Key' engine -- just install it and go have fun.
