it is auto trans and it has 4.10 do they sell the lifters as well?
Yes they sell cam/lifter kits. Your axle gear ratio is good, but the auto trans with only 3 gears may work better with something like the 207/213 duration at 0.050 rather than the 213/220 that the 60401 cam offers. I would recommend a split pattern cam with more exhaust duration than intake duration, like the ones we've been talking about, because they would work the best with stock exhaust system.
I would suggest asking them if they can grind you a small block mopar cam with 207/213 duration at 0.05, with 112/108 lobe separation angle. They grind a cam with this spec for small block chevy, grind number 01/250/260, ask for that grind number. It would have a smooth idle, uses the same rocker ratio you have, is not too aggressive so would last many miles.
Their website says the 207/213 grind has:
The best torque cam. Expect strong low to mid range horsepower and torque gains. Excellent for RV type vehicles, pleasure boats or towing applications.
If you want more of the performance lumpy-idle sound, then maybe stick with the 60401 cam, with 1000-5000 rpm range. Probably not the best for towing, Won't pull strong right off idle, but would sound more performance if thats what you would rather have.
