Is a tighter lsa better for low to midrange torque? I'm not worried about idle quality. I haven't got a car yet but I'm trying to get a decent idea of the route I want to take. I doubt that the engine will ever see over 5000 rpm's
Why only 5000 rpm? If your main interest is just low to midrange, a stock 360 magnum might be a good choice. No sense in building an engine that makes power past the point of where you are willing to take it.
