Cars Running on Timing Chains instead of Timing Belts

[Bursty-dude]

Twin = two
Double = two

Not rocket science.

I wonder how Magnum or Jaws will explain a VR6 motor which has two cams for all 6 cylinders (one cam per bank of 3 cylinders).
One cam operates the intakes AND exhaust on one bank, same with the other bank.

And it even says "DOHC" on the plastic cover on the intake manifold. Wow! Must be some true rocket science going on there!
