The Holley Stealth Ram kit for a Chevy small-block comes with everything you see here. Depending on what horsepower rating your engine is putting out, Holley will include different pound per hour (PPH) injectors. The manifold, plenum, throttle body, wiring harness and connectors, sensors, fuel pump and filter, and ECU all come together as a package. You'll also need to pick up new throttle cable linkage and tranny-kickdown linkage yourself. Plus you'll need a distributor designed for a factory TBI Chevy small-block, as an HEI unit will not work since the cap diameter is too large.
