Re: 9-main bearing inline eights

All the aluminum crankcase 8-cylinder models were 9-main bearing. Bores varied with the year and model, 3-3/16 for the 320 version, 3/3-8 and 3-1/2 for the 385 version. Stroke was constant at 5 inches. There was no 316 cubic inch model to my knowledge. You might also want to note that the 1st and 2nd series "big" Eight has a different crankshaft configuration and consequently a different firing order. As Ross says, get any Motor's that covers the 30s.
