Of monobloc construction without the exhaust ports, guides. etc. 137½ 205. Rockers & Push-rods. These will be the same as for the Bentley. 5 5 TOTAL ENGINE WEIGHTS ARE = 620¼ 653. The O.H.I. engine is practically the same as the Bentley, the O.H.V., however, being about 33 lbs. heavier. Items chiefly repaying attention are the spring drive and the electrical parts, it being assumed that the flywheel and crankshaft assembly cannot be touched.
