That was available with a four barrel, a tri-power or dual four barrels.Definitely enough to wake up a Studebaker. Must have been a laugh with the early three speeds and rear ends. It was common to take a car like the early Avanti and Cadillac the thing and it would have looked original. After Studebaker quit building cars, the 300 horse 327 with the AFB was a very logical alternative to a big heavy block in an engine design that must have weighed 650 pounds if an ounce.

Greg,
Charles Kettering worked for GM during the 1940's and designed the Cadillac engine that was originally produced in 331 cubic inch size and used in the 1949 models which was the first overhead valve engine used by Cadillac. This series of engines were made in 365, 390 and 429 sizes in later years. It was replaced in 1968 by a new design of 472 and 500 inch engines. I have not worked on any of these but have seen them in machine shops and they did not look like the motor I had in my Studebaker Silver Hawk.
thanks, Roland
