I have been looking for either a pontiac gtp or regal gs for awhile. I finally managed to track down a 1999 buick regal gs. Is there anyway to get away with mabe a 3.4 pulley adding just a intake,180thermostat,dp,and autolite 104's? At least for awhile? btw I had a mild cammed firebird lt1 before this with a built trans, it is nice to drive something and not always have to get gas lol!
