can anyone tell me what the base timing and the total "all in" advance should be for the stock chevy 153 engine?.....
I have a GM 181 engine that I have tried to set up with an EST distributor, but I cant get the distributor to time correctly.... there are too many degrees between base and "all in".... so when it sets at idle and runs and starts good, it pings terrible... when I adjust it so it doesnt ping, it idles rough due to the initial timiong being set too low...
It has been suggested to change from an EST to a HEI system, which I was told would give the dependable electronic ignition, but with the mechanical advance, which eliminates the need for a special timing procedure to get it set right....
HEI distributors listed specifically for the 181 is super rare, so I want to find out if the advance cure is correct in a HEI unit for the 153 is the same before spending more money on another system....
but I dont want a distributor with vacuum advance, but a full mechanical advance...
and...does anyone want a good, very little used 4 cylinder Delco EST system with ALL new components???
