Here's what I got going on. I have a 1984 d100 custom with a /6 with a 4 speed. I had to do some rigging to get it going just not enough power for me. I just can't decide whether I want a 318, 360, 350 v8 or just putting a cummins. I'm not going for major horsepower just a nice little rumble you know. So my question is what is the easiest way to do this?
