Help me to choose the right cam

36s and 3.55s?
Granny gear or no,I don't see that as particularly fun......
Without knowing your tranny ratios, tho, it would be difficult to recommend an alternate ratio.
Sounds good tho; 6000 pounds, 440,torque cam.
IMO;
I might consider sacrificing some torque and put a decent gear in it.And not using granny on the street.
