Hey Ron,
You are right, the buick 322s were not used in the light duty Chevy Trucks. But, as Bill(Longbox55) had said earlier in the post, 322s were used in Chevy's 7000-10000 series trucks beginning in 1956 and ending in 1959. And as Bill(Longbox55) had also said, it was standard on Chevy's tandem axle trucks.
Thanks for brining up the good point.


If it ain't a Chevy, It ain't nothin'.
