I think it costs close to $500 for the carb mod, and that's after I buy the carb. I really want to do all of the work I can myself, but I want to take precautions to avoid burning a piston or rings. I know there will be some risk involved, but I don't want to start without a plan. Do you think that supercharger will be a good choice? I thought I could afford to try it out b/c of the low cost, and swap it for a purpose built one somewhere down the road.
