What is an AMCA National?
AMCA Nationals are purpose-built modified race cars based on American Dirt Modifieds.
All chassis feature a HQ-WB Holden front clip and drivers have the choice of running either a Holden V8 253ci engine, which produces around 340 horsepower, or a Chevrolet V8 350ci crate engine, which produces around 350 horsepower. Drivers also have the option of running a standard Commodore BorgWarner differential or quick-change differential.
With the tightly structured rules, such as control tyres aimed at creating a level playing field between all competitors, AMCA Nationals produce close and exciting racing that is fantastic to watch and always pulls a big crowd to the fence.
