Extremely high strength alloys were the specialty of Francis Dix, the “Dix” in BRODIX. His family had a long history in the foundry industry. Along came J.V. Brotherton the “Bro” in BRODIX and married Paula, the daughter of Francis and Dorothy Dix. J.V.’s hobby was racing automobiles.

Brotherton had a fascination with cylinder heads which led to the production of an aluminum Hemi head in 1971. Mopar reintroduced their aluminum Hemi head in 1972 and gave them to their racers. Needless to say, this was not a good thing for aftermarket Hemi sales. Regrouping, a small block Chevy head was made in 1973 and the rest has been history. The ability to make close tolerance, high strength castings has been the benchmark of BRODIX.

Brodix Cylinder Heads - Performance UnlimitedIn 1996 BRODIX developed and produced an aluminum small block Chevy engine block. Soon after, it became the standard by which all other blocks would be measured. Due to the overwhelming success of the small block aluminum block, BRODIX then developed a big block Chevy version in late 2003. In just a short period of time, this new block has achieved amazing results including a win in Super Comp at the 2004 U.S. Nationals.

BRODIX started with a very basic 23ƒ small block head. Subsequent development led to numerous versionsBrodix Cylinder Heads - Performance Unlimited and designs. In 1987, BRODIX developed the -12 15ƒ valve angle head that eventually proved to be a versatile head for sprint cars and several other applications. Even today there are BRODIX customers who still use this cylinder head with good success.

Over the years there have been other valve angles, valve centerlines, and several different port designs and shapes. Today the BRODIX line up ranges from the revolutionary IK 200 heads to all out raised port small block heads. There is an equal spaced exhaust port version, the “BD” Series, which is a total redesign of the small block Chevy.

The company has produced thousands of big block Chevy heads for several years. The big block lineup goes from the RR BB-O all the way to the PB 1200 series of Pro Stock style heads.

Mopar heads are also available in several versions for both the A and the B block.

For the last ten years, they have produced “spec” heads, which are manufactured to an exact specification for different racing associations.

A spec head is designed to control costs and development of heads for certain classes of racing. The company produce heads and manifolds that can be checked by the racing associations for all dimension and design parameters. Engine costs and reliability are, in the main, controlled by the design of the cylinder head. Cylinder heads are considered to be one of the factors that can control the cost of racing.

BRODIX produces a large line of High Velocity intake manifolds for small and big block Chevy engines. These manifolds are known best for their “out-of-the-box” performance.

The company has enjoyed many successes over the years in every form of auto racing. Performance Unlimited are proud to be a distributor.
