Keeping pace with the
increased popularity of the fabled 426 Chrysler Hemi, Aviaid Oil
Systems has introduced a pair of new oil pumps for both wet and dry
sump applications. They are designed to fit both OEM cast iron or
aluminum blocks, as well as aftermarket “Hemi” racing blocks (BAE,
Keith Black, TFX, etc.).
The smaller of the two

(gallons per minute), and can be adjusted to deliver up to 300 PSI
pressure. It has a 5/16” female hex drive.
For racing applications where 20 to 40 GPM flow is needed, like Top

best bet. It can also be adjusted to provide oil pressure in a 0-300
PSI range. A 7/16” male hex drive is utilized.
A key feature of both pumps is their ability to be rebuildable in the
field. They are offered with aluminum or cast iron pressure sections,
with sizes relative to GPM flow desired.

was supplying lubrication systems to the likes of Carroll Shelby for
the original Cobra, and to Ford for the LeMans-winning GT-40. Aviaid is
