i just paid 300 bucks for a 98 454, its smokes. but it will be going in shop in two weeks. it has almost brand new 26'' 589s on them. it has plenty of clearance for 28s with no lift so thinking about getting them. most likely in 589 or outlaws, or maybe even a mudzilla, but i heard they are heavy. so will it trun 28s pretty good since it has a low range. aint really no aftermarket parts. but i will get a jet kit after i get my snorkle and tractor pipe put on
