I am building my first pro street chopper. So I will probably be using this forum quite a bit.I currently have a voo doo rolling chassis plus. I know what I want the final product to look like.I have some parts to swap out/trade.If that can be done on this site? My initial question is engine selection.Rev tech/s&s/ultima/or harley.I currently drive(24yrs) a 83 custom semi-stock superglide(fxr).Please give me feedback on pros and cons of these different engines.Long engine life and dependability are important since this bike will be given to my son eventually.(hopefully a long time from now).Any advice will be appreciated.
