slowZ28 Posted April 4, 2009 Report Share Posted April 4, 2009 I have a 4-hole throttlebody that has been machined to provide the maximum amount of flow through a 4150 flange manifold. It is now a 2 blade throttlebody that will flow over 1500 cfm. Excellent piece for a big block. A custom idle air control housing was machined to allow the most flow. It utilizes an LS1 IAC motor to bypass the most amount of air possible. This allows large aggressive cams to idle under 900 rpm! The center area has been machined so the center stud is no longer present. Instead a separate bracket is included to hold down any standard carbeurator air filter assembly. This unit will outflow anything on the market including the Wilson Manifold 472175 throttlebody which sells for over 700 dollars without sensors. I am selling this throttle body for $600 shipped including the throttle position sensor, IAC housing, LS1 IAC motor, filter bracket, progressive throttle linkage and return springs.
