Pistons and rods become one in the war on power. There's less piston in order to improve reciprocating weight, reduce internal friction, and increase displacement. This connecting rod is an MPG exclusive because it's actually a 5.470-inch Honda race rod ready for installation in your small-block Ford. This gives MPG a good rod ratio and longer dwell time at each end of the bore. Note the smaller 0.870-inch pin and 1.848-inch journal diameter. Why? To reduce internal friction and free up some ponies. This calls for a Scat special-grind steel crank from MPG with smaller rod journals. Relax-it's all about making intelligent power.
