So I'm gonna' try and snag one when I can, gonna browse web and look for one that's on the quieter side, at least at idle and not too screaming on the streets. Sooooooo, What does one look for for when buying one used?? Whats low miles considered?? Price range limits of buying used?? Normal price to rebuild one?? If i find just the SC is it hard to piece together or just stay away from that?? Anything featured that makes life easier, performance or up keep?? It would be a low boost application because of my .30 milled heads, btw would that help it being quiet because it wouldn't work as hard??? ***looking to get boost certified and you guys know your stuff, so thnx again!!!
