alright, thanx alot. i planned on getting hedman headers, a cool air intake, and having a local exhaust place bend me up a new dual exit exhaust exiting infront on the rear passenger side wheel. i got to do some more reasearch before i do it, about tubing sizes and backpressure and what not. i planned on getting this lowering kit ( http://store.summitracing.com/partde...DJM-KS3001-3-4
) from summitracing.com. i need my **** end of my truck to go down at least 2 more inches than the front but i guess that kit will do. i want it level. so what all is necissary to make my 4.0 pump out power like Gerry's and Jimmy's.
