So my truck is a '95 k3500 dually regular cab long bed. It's a 4x4. It has a 454 with only 62,000 orig. miles. It is a manual and is a stock engine. I have about $3,000 or so that i would like to spend on it. Do you think i could get a decent amount of power gains? if so what would you recommend putting into it? and about how much HP/TQ could i gain? Thanks for your help i really appreciate it
