    Hey guys, kinda new to these forums. I have a 94 chevy pickup that we just rebuilt. Bored 40 over with vortec heads, roller lifters, and roller rockers. When we start the engine it idles and run awesome, but when you go to romp it, it falls on its face. We checked the MAF sensor, rebuilt the throttle body, checked the timing, and checked the vacuum lines. Can't figure it out. I should tell you that this issue was present with the old engine as well. We thot that we would get the new engine in and see if that would help. Not sure if we have a badf computer or fuel flow problems or what. Def could use some help./ Thx​
