Back to the question, how the late 336 are timed. PJ has the numbers? PJ?????
I'm afraid it is so long since I built the engine that I have lost and forgotten the figures!
I have an old piece of paper with some figures that I have written down and these give lobe centres of 95 inlet and 106.5 exhaust, but I cannot be sure where they came from. The opening and closing points I have written down add up to 280 degrees of duration which does not really add up to a sport cam.
I can see that when I have some time, I am going to have to get out the dial gauge and degree wheel and see what's happening inside my engine.
