3 speed would like lower rpm's hwy?

the cheapest way is a taller tire. but you would need 15" wheels... wheel vintiques sells a 15 x 6 and 15 x 7 small bolt wheels... then throw a set of 235/70-15 on there.. it will mellow then 3:91 gears quite a bit. still probably have $500 into it though... there really isn't any real cheap way to do it... http://wheelvintiques.com/shopsite_sc/store/html/page52.html
