In Pro Modified racing here in the United States, there are a handful of engine combinations that we expect to see. The most common are hemi engines with various power adders, along with mountain motor nitrous combinations. However, down under they do Pro Mod a little differently, and it’s just as wild and rowdy as we do things here in America. Case in point, PAC Performance Racing in Australia recently unveiled a rotary-powered 1969 Camaro Pro Mod to compete in the Factory Extreme class.

Sam Sadek is excited to be back behind the wheel and driving his new PAC Performance-built Factory Extreme car.
Built for Sam “The Godfather” Sadek and his Sadek Racing team, the ’69 Camaro was shipped over from the United States. PAC Performance co-owner Rocky Rehayem says the car had run in the 3.6s in the eighth mile in the United States with a different engine combination in Pro Modified trim. Once at the PAC Performance facility, the crew got to work modifying the chassis to accept not a three rotor engine, but four rotor monster mill.
PAC Performance started with a proven chassis sourced from the United States and added one of its custom billet twin turbo 4-rotor engines.
Although Sadek’s Camaro appears similar to many Pro Mod race cars here in America, its powerplant is quite the departure from what we are used to seeing. Under the nose is a PAC Performance-built billet 26B 4-rotor that is packed with many custom and one-off components Billet By PAC is known for. The power adder of choice is a pair of Harts turbochargers, and a Motec M150 system keeps everything under control. “This is new territory for us. We’ve had it on the dyno a number of times over the past few months, and we’re really happy with how things are looking,” Rehayem says.
Transferring power from the screaming four rotor to the rear tires is an air-shifted Liberty transmission that’s mated to a Quick Drive unit. Rehayem and the PAC Performance team believe the Liberty and Quick Drive combination will suit the four rotor well. This engine and transmission combination is somewhat uncharted territory for the Factory Extreme class. “In the past, we weren’t allowed to run a four rotor in the Factory Extreme class as it wasn’t from a production car,” Rehayem explains. “However, with all the piston guys now using custom billet blocks and heads, the rules have been opened up…
