Interesting. I worked in Morse's R& D lab at about that time. I spent some
time around the test set-up for the Ford FE 427 SOHC timing drive, but
never saw anything for a Repco/Poncho! They must have done the work at
their facility in Oz, and not mentioned it to us!

Heads were cast aluminum,and Lucas fuel injection was used.
