I have never bought a cam for a truck and could use some suggestions. The truck is an 07 NNBS VMAX 4WD. It has Long tubes, 2600 stall, 8 inch lift, and the rest of the **** in the sig. I tow a lot and would really like to see the power increase in the low end, as the truck will never see a day at the track. I rarely even get over 4500 rpm and would like to get as much low end as possible. I was alos wondering what are the best rods and springs to throw in there. The help is much appreciated.
