Change the stroke. My "258 that looks like a 216" will have either 5/16" or maybe 3/8" extra stroke. I'm not looking for more RPM, because that's a virtual impossibility. More leverage on the crankshaft translates to more low end grunt, and less off a need to downshift. However, it's about the most expensive way to get that extra torque!
