To some, putting a carburetor on a GM Gen III V8 is a step back in progress, but to many enthusiasts that do not want to run high pressure fuel lines and miles of wiring, this is a giant step in the right direction!
GM Performance Parts and Edelbrock now offer cast aluminum intake manifolds that allow the installation of a carburetor on these advanced small blocks. But, without the EFI's ECU, they needed a controller to fire the ignition and MSD stepped up to the plate.
This compact ignition controller is fit with matching factory connectors for a direct installation. Only a handful of connections are required; the coils, crank sensor, MAP
sensor and the cam sensor. This Controller also allows you to map a timing advance curve with MSD’s easy-to-use Pro-Data+ software. Other features that you can set include a two step rev limiter, a vacuum advance curve for cruising economy and even a step retard in case you want to add a little nitrous to the mix.
Can be used as a stand-alone ignition controller in conjunction with factory EFI system by using adapter harness #121-8886, sold separately below.
