I know I've been dying myself for some better gearing options ...I've thought about the 3.27 and I've also thought about ripping it out and going with a ford 9inch like Jim said and even thought about doing his Challenger option question is can Rudy or euro charged get the tcu to work with it I'm about to try it soon lol getting the itch to hurt some feelings at the drag track lol I'd love to have anywhere from a 3.91 to a 4.56 or something lol
