My truck is a 1972 chevy made primarily for the bogs. Its just a straight shot with it right to the floor trying to get to the other side. So higher rpm is beter since you need as much wheel speed as posible. Yes I could go with a big block with high low end torque and higher gears, but I have so many 350's. Having that much power is no real bid deal. I already have 2 1/2 ton rockwells and 44 inch tires the only thing I would have to do is the trany. I have a th350 now but iam shure it wouldnt handle it.
