 For ease of operation and tuning on the dyno, Craig and Bob chose a carb with some race features. The new model 4150 HP Holley mechanical secondary 750-cfm carburetor lacks a choke horn for the street, but does have threaded air bleed adjustments to make tuning easier. Other features include: smoothed venturi transitions for increased airflow, stainless steel throttle plates, notched floats, and Dominator style fuel bowls so the fuel line can be attached to either side. MSD’s Pro-Billet Ready-to-Run 6061-T6 aluminum distributor is easy to install with just a few wire connections, it has a maintenance-free magnetic pickup to trigger the ignition, eliminating points, and has an adjustable mechanical advance, not to mention other features to increase output and durability. The as-delivered setups of the carb and ignition will be used to break in the engine.
