That what I was saying about the gearing and converter choice affecting your shift recovery rpm. You can go bigger than TR220 with the 6.0 if you get your compression up by either swapping heads or milling your 317. If it was me with the gear you have and the fact that you have a kit I would do this. 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.
