Rodney, one thing that has come to mind since our last email session on this car, I remember talking with Rod McElrea @ a Teretonga OSCA round & he had had a problem with the oil pump drive shaft or gear in the Boss 302 motor in the Ex Fahey/Riley/Armstrong car, Im fairly sure he told me at the time that it was the motor out of Kevins old car as it had a unique oil pump setup, When he bought the MKIV Cortina off me this engine was transplanted into it as he bought the Boss 302 headers from my motor at the same time since those in the mustang would not have fitted. When the Haig car was raced by Christie Morris the following season it was fitted with one of the 5? Boss 302's that PDL had bought in from the USA, as I pointed out to you I believe Lawrie Bruce might have actually bought that motor as a year or two later he offered me the twin dominator manifold the motor was fitted with.
cheers
Jac Mac
