Re: converting a GM non computer hei distributor to a computer hei

[WEG1192@aol.com]

In order for the timing to be advanced, the reluctor has to "outrun" the 
distributor shaft, so when accelerating or cruising, the distributor shaft is 
pushing the reluctor shaft essentially keeping them in contact. Therefore the 
only time "slop" enters the picture is on decel when the shaft is actually 
slowing down and the reluctor "might" lag a bit due to angular momentum. If 
sloppy timing is a problem on decel, then you could weld them together for 
insurance, but I've been running just strong springs for 5 months with no 
problems. I don't want to permanently lock down the mechanical advance 
because I may want to map the distributor curve in the chip at a later date 
just for kicks to see how far off the non-computer curve is from the computer 
advance curve. On my Jeep, I found the non computer distributor advance curve 
to be about all the engine could handle.  JW
