Get your hands on a set of 243/ 799 heads and have a good valve job and have them milled to about 60 CC chambers and use a .051 headgasket. Get with a reputable co. and have them spec a cam that will work well with that head and your truck intake. Something in the 220 - 222 intake and 226- 228 exhaust range and probbaly around .580 -.600 lift LSA 112- 114 on a 108 -109 ICL. Overlap is real important as far as how it makes it power and keeps your dynamic compression up so that it has really good throttle response. I am by no means a cam expert , but one thing I do know is that a cam designed for a lighter car will work , but it will not make optimal or the type of power you need for a heavier truck. That is why it is worth it to let soemone who knows what they are doing to have you a cam ground. Match it with a converter that puts your engine where it needs to be in its powerband and you will have a much quicker truck. Stall speed alone is not the only aspect of converter selection that is important.
