Hi there. For the carburetor swap out, you will need to have a least a CFM of 850 or 950 for a big block GM engine. If you are concerned about fuel consumption, then you could do a CFM of 750 to 800. This will make the engine run leaner but give you a better fuel mileage. Click here for the carburetor that is recommend for you.

Since you are planning on using an MSD ignition system, I recommend using a more power full spark plug than the original OEM specified spark plug. Click here for the type of spark plugs that will work with the MSD ignition system.

Ignition MSD is a more advanced ignition system and delivers more burning power to the cylinder by applying more spark at a given time. Click here to view the recommended MSD systems for your vehicle.
