This listing is for an MSD/Holley Intake Manifold/Ignition Controller Kit for GM LS Engines with Rectangle Port Cylinder Heads such as LS2/L92 Style; Works with 24x with 1x Cam Sensors and 54x with 4x Cam Sensors
Holley Single Plane Intake part #300-131 - Includes Intake Seals
MSD Black Programmable Ignition Controller part #60143 (Includes Harness)
Note! This kit will not fit with the 24x reluctor wheel when a 4x Cam gear is swapped, but a separate harness is available to adapt that, MSD P/N 2279
We put this kit together at SK Speed to simply the install of a Carburetor on a Cathedral Port LS Engine. With the Holley Single Plane Intake, you get a standard 4150 Flange which accepts most aftermarket Carburetors. The MSD 60143 Ignition Controller allows a simple plug-n-play installation affording easy control over the factory coils. The controller is also programmable giving total ignition control when needed.
