Everything Sunder said...and.. The only reason I can see ANYONE on this site stroking their engine is to produce more torque below 2500 rpm. Improving the off idle performance is what stroking the six is all about. NOT higher rpm. BIG holes and small rods is what makes rpm advances.. Best example I can think of would be the 69 302 sbc. A 350 cylinder and a 283 rod and crank made for 302 cubes and if you dared 8,000rpm. That thing would just keep climbing.. But stroking a six is backwards from the 302. We increase the stroke to make more grunt.
