Got a NA bracket all cleaned up, painted and ready to go. Also have the appropriate plug ready to wire in but trying to make last minute decision on alternator . For those of you who have done this, Which alternator did you use, the 5-1/4" or 6" case? I was thinking the smaller alt was the one that was used until I discovered that most of the smaller ones are only 105amp and the 6" is the 140amp. wasnt to crazy about using a physically larger alternator because of not only weight but I thought the smaller would look better. Does anyone have any pics I could see who are using the 6"? #1 priority is bumping up my voltage but Ive seen some of those obnoxtious looking giant Caddy alts and not to crazy about going with that look, if thats what this 6" one is like.

TIA
 
FYI it has been known that the smaller alternators are more prone to burn out faster because of there size and lack of cooling.
