Gary Conley built several machined V8 engines. He also built a few V4, V6 and V12 models. In 1988-89, he fabricated the molds and patterns to produce a casting kit for his V8 and made it available in several variations. Most commonly, it was supplied with a carburetor, but later versions included multiple carburetors with velocity stacks (specially configured tubes that increase the velocity and direct the air into the carburetor). Other variations came with miniature superchargers, such as the Roots-style 671 blower commonly seen on hotrods and dragsters in the 1960s. This engine is 8”-long, 6’-wide, and 6”-high.
