They are stock specs bar Pacemaker headers and Breklee Exhaust, and have a few changes mainly for reliability. The Fords' Coyote engines are imported directly from the 'States by Halsted, have a different sump, oil-pump and pick-up, alloy subframe, PWR radiator and header tank, SS inductions intake, Motec ECU and are limited to 5800rpm. Weights are 1810 and 1815kg I think.
Holdens get a double-row timing chain and Motec ECU and are limited to 5900 rpm.
All the engines, the control wiring-loom, injectors, fuel rails, and ECU, are sealed and Halsted supplies the whole thing ready to go including the dyno sheet.
I think the Fords get a fully-floating conversion on the rear axles, both the diffs are spools, solid -centre button-clutch, bushes replaced by neoprene, DBA rotors and alloy hats, Brembo calipers, Quadrant Suspension Bilstein/coil-overs, Fords get a special tailshaft, wheels are Bob Jane, tyres controlled and marked, and almost everything is controlled and has to be supplied by specific suppliers.
All the engines are built and dynoed by Halsted and are supposed to be identical power/torque to within 2%.
There's an amazing number of detail restrictions but that's the guts of it.
