Australian Trans-AM



Australian Trans-Am is open to any 2-door, 4-seat, rear wheel drive, V8 powered American production vehicle built from 1963 to 1974. Therefore, it scoops up cars such as second-gen Camaros, Mustangs, Plymouth Cudas, AMC Javelins, and Pontiac Firebirds.  Australian Trans-AM has a good set of regulations based on the original SCCA Trans-Am Series, though with some modifications in place to keep costs down.  Engine restrictions are put in place to keep horsepower levels down, and to preserve the life of drivelines and other components.  


Three different classes first are the Trophy class.  This is for over 5-Litre cars who generally fight for outright victory.  Then there is the Sportsman class for over 5-litre competitors with a smaller budget and who don't generally feature in the top positions.  Thirdly is the 5 Litre class is for cars with an engine capacity no greater than 310.8 cubic inches essentially, a 302 with a maximum overbore of +0.060.


All cars must run on commercial 98 Octane fuel, with maximum 200cc cylinder head intake ports, and maximum 11:1 compression, a combination that makes for some spectacular flame spitting antics on track.
