For an Apple-to-Apples comparison, compare the New Engine Kit (cylinder block, crankshaft, and connecting rods) to similar refurbished original parts.
Compare the new engine's 16 pressure-fed bearings to the original gravity and dipper system, compare the new 2.00-inch rod journals to original 1.50-inch rod journals, compare 5 main bearings to 3 main bearings, compare 8 crankshaft counterweights to none, compare the radial lip rear main seal to the slinger, etc.
Compare the fact that the "New Engine Kit" is manufactured in a modern factory that manufactures 100's of thousands of engines per year to a small shop with antiquated equipment.
Compare the fact that the "New Engine Kit" is made from materials that have improved over the last 90 years.
Several new engines are running. One has about 7000 miles after being driven across the USA twice. Another has about 3500 miles after being in the Great Race (car #35).
See www.modelaengine.com for more information including engineering details and testing abuse (3100 RPM for 6 hours on an engine that was just assembled), and the hill climb.
