THE engine considered in this paper is an eight-in-line of 3 1/16-in. bore and 4¼-in. stroke having a piston displacement of 250 cu. in.After comparing the performances of the “FD” and the 8-250 engines, Mr. Sparrow relates in detail the changes made in the engine under consideration and states the results obtained by tests, also commenting thereon.The subjects considered include valve timing and lift, intake pulsations, distribution, compression ratio, ignition, blowby, oil consumption, cylinder-block cracking, valves and valve seats, valve springs, pistons, crankshaft failure, connecting rods, and bearings.Numerous data are presented in chart form, together with other pertinent illustrations of the subjects discussed.
