Best of my knowledge CHEVY never used Pontiac engines. The General
Motors Truck and Coach Division used Pontiac V8s in their gasoline V8
equipped light trucks (less than 2 ton). In 55, 56 and 57 they were
almost identical (bigger dishes in pistons for even lower compression
ratios and Bendix/Stromberg carbs) to same year Pontiacs. In 58 they
used the same block as Pontiac, but only bored it to 3.875" giving a
336.1 cubic inch engine instead of Pontiac's 370. In 59 they again used
the same block as Pontiac, but only bored it to 3.78" giving 336.9 cubic
inches instead of Pontiac's 389. Cranks, heads, rods, etc. were the same
as same year Pontiacs.
