Despite being built in 1987, its interesting to note this engine is fitted with an EF intake manifold. I'm not sure if that was added later for presentation purposes, or if it was being developed in tandem with the twin cam head and eventually made an appearance in 1994 for the EF update.

There's a camshaft position sensor on one of the cams too, you can see it in the timing cover - must have been thinking about sequential injection and ignition in the 1980s?

The Buick V6 in the Grand National had sequential fuel injection back in that era, not sure if the Buick/Ecotec Commodores do or not.

Sequential injection made its way onto the AU - under 3000 RPM I think due to lack of processing power - I think I'm not 100% sure.
