1956 Pontiac Star Chief Custom Convertible 317 V8 Engine

The Pontiac was only a little bigger than the Chevy, but the 317 (316.6) cubic inch overhead valve V8 was definitely stronger than Chevy's 283, and this particular non-numbers cast-iron block was bored to 350 cubes and rebuilt to factory specs that exceed the original 227 base horsepower ratings. Add in the factory-style Rochester 4-barrel carburetor and custom Cadillac air cleaner finished to match the continental kit, and you have a high-profile cruiser that can run with the best of them.
