Apart from cutting a hole in the bonnet, not that much really, a cable trottle linkage. Run the 2 inch blower drive. with a short water pump. And a good radiator and fan to pull the air through. One thing you will find with blowers, the engines run hot when under boost. Recheck your timing and make sure that your ignition can give you a good spark. Now bar in mind this is a street fun combination, and not a hard core racing engine. But who knows ? you could get addicted to the kick in the pants feel that comes from blowers, and like some of us go all out. But have fun firstand start at the bottom rung on the ladder.
