Inliners International Forums General Discussion Engines GM 153ci timing questions... total advance

I am far from an expert on this, however somewhere I have the chart for the 153. Initial timing and advance vary somewhat by year and application, but I wrote down the factory spec for the 153 that's in my CJ2a, which the factory originally put in a '68 Chevy II, as follows:
0 deg BTDC at idle
total advance 43-1/2 to 47-1/2 at 2500 rpm with the vac, 20-1/2 to 22-1/2 at 2500 centrifugal only
Dwell at idle 31 to 34, variation of 3 between idle and 1750 rpm
Vac at engine should be 17-21 inches at 750 rpm with the air cleaner off and the vac plugged
The chart also has spec to check the mechanical advance, but that is dependent on the particular distributor you're using. I'll look around this weekend and see if I can't come up with the chart.
If anyone has a spare rear sump oil pan for this motor I'd be very interested. The one in my jeep has had a hard life.
