I picture paints a thousand words has never been more true! Watching that explains so many ways of creating mechanical movements in ~4 minutes. That would be impossible to do so quickly in text. I dont want to have to source replacement gears for some of those mechs, though!

Is that a V6

Yes, old VN/VP type, these were quite limited in reality due to average at best "one fits all" tune, stock 60mm TB with no manifold mods allowed and a rather weird un-optimized flat tappet cam with not a lot of lift but overly excessive duration, the cam was designed in the late 80s and left unchanged.

They produced by the time head refinement was down pat at good but not best 340hp @ around 6800 rpm and peak torque just under 5.5k of 400Nm.

With a custom large TB and elbow, ultra high compression ratio on E85, optimized theoretically smaller cam and some manifold porting for good measure I figured a result of 390Hp @ 6500 and peak torque @4.5K of about 480Nm

Jason loved those things. The tune for them is on here I think it came from him originally.

yes it did, I recall the file was called 7200 crazy spark or something lol

iirc it was just a fixed 20 odd º across the table.

EDIT: power of google finds the original file from Jason.

There is a write up about the development of those formula Holden engines somewhere.
