Wanted to ask a couple questions again!!! I was at the junk yard and saw a newer stang and was wondering about the mass air. I know they do alot of the conversions with the 5.0's. But is there any difference with or with out??? I plan on running my roller with my head as soon as i'm done porting.. I'm trying to get my hands on a puter if i can find one and wanted to know when i get it how do i know if it needs mass air or not??? This is n/a by the way can't seem to find any turbo motors around these parts..
