electric or mechanical?

If your mechanical one is working fine why change unless you plan on pumping more fuel to feed more horses..I have an elect back up on my 360 ramchgr but run on mechanical and the 440 dart is set up for elect but thinking about a mechanical[hi-vol 7-8lbs. pressure] for the street...mechanicals generally less probs for most part...elect generally used for higher hp and fuel demands and for use in fuel injected engines....
