Re: Timing Question about 5682s

Let me add my two cents worth. Firstly the engine number. With my car the engine number is exactly the same as the body number stamped on the door placard. Secondly, timing. I have a Pertronix kit fitted and started out with the timing at 10.5 degrees, backed it off to 10 and am about to go to 9.5 as I've heard some very occasional pinging, which suggests that it's not far off the right spot. At 10, I can drive for ages without hearing any pinging at all but, as I said, occasionally it happens. Perhaps of interest to us aussies, if I am to hear any pinging it's more likely to occur when I've had to put Shell petrol in the tank. Over here we have three basic grades of petrol - one standard and two premium, and I think the RON octane ratings are 91, 95 and 98. I usually use the mid range 95 as the car seems happy on it, and she seems to have a particular preference for BP. Cheers, John
