Are you looking for faster 0-100mph, or faster top speed? depending on the type of driving you are doing, you may want to look into different differentials (gear ratios). Another consideration may be an electric fuel pump...I noticed the mechanical in the pic. I believe the triples carbs can benefit (predominantly at high rpms) from a low pressure electric pump and fuel regulator. Sometimes the mechanical pump can starve the carbs @ high rpm's. just my $.02
