I have an 84 full size with a rebuilt 351w. I put an edelbrock performer maifold on and an edelbrock 1405 performer carb on. I just installed the rebuild motor this weekend. I found out that trucks dont run on mud water for very long. I had to put a new engine in it because of all the work I've done to it. I have a three inch body lift, a two inch block lift, a inch and a half spring kit for the front, 35 inch BFgoodrich allterrain ta/ko's 15x10 chrome U.S. Wheel rims duel sunroofs and a kaylen soft top. Soon I'll be getting some dynomax headers.
