I've been building mostly V8s for the last 20 years. My truck has a 1959 235 in it, bone stock. I use it for hauling stuff, towing, etc, it's a work truck. I want to keep the 6, not likely to run across a 261. What I'm after is maximum torque. It can be done making horsepower at 3000 rpm. The small carb and small ports help velocity, helping low speed torque. Raising compression will help some too I know. I may shave the head a bit to get it to 9.0:1, as I still want to run 87 gas. I am also thinking of a cam, with 112-114 lobe center, moderate lift and short duration. I would think a stock exhaust manifold would be fine since I'm not trying to get rpm out of it, so pressure there should be minimal. Any thoughts? What is a good head casting number? Cam suggestions?
