Yeah, I forgot the vettes had special side-draft carbs and intake, and a special vette split exhaust manifold. Supposedly had a different solid-lift cam than was used in sedans. Dont know the head casting #. Rated at a whopping 150 HP. The 53-54 vettes were only available with that special 235 and a cast-iron 'glide trans. In '55 they went to 12 volts and a small 265? V8.

During the '54 model year a camshaft change was made which increased horsepower from 150hp to 155hp in the Blue Flame Six engine.
The '54 vette weighed in at 2,886lbs.
