Buckeye, Those 322 Buick engines, were used in the '56 & '57 Chevrolet, Heavy Duty Line, of trucks. Series 9000 (LCF's), & 10000 (Conventionals). The '58's, & '59's, used the Chevrolet Big Block 348. Mike Boteler, knows more about these trucks than anyone I know. He visits this forum often, & he'll correct me if I'm wrong, & can tell you more about them.
