4 litre, dual continuously variable valve timing, 24 valve, turbo charged straight 6.
The basic bottom end architecture harks back to the time of the dinosaurs, but they do alright. ;-)
VERY under tuned and easily upgraded. Unfortunately the BA/BF models used an inlet manifold very similar to the NA engines, but with the dual length butterflies removed. This kept the throttle body pointing over the top of the engine and so the post intercooler plumbing goes over the exhaust manifold..........
Similar to the air feed for the turbo, due to the Falcon having it air filter on the left hand side of the car.
The FG (followed the BF) cars had a much simpler and compact inlet manifold that let the intercooler plumbing avoid going over the exhaust manifold.
