Performance Distributor in Stock Engine
Service manual specs graphed look like this.
If the distributor is advancing close to the top line (most likely with a high milage distributor) , setting initial for 15* at 600 rpm, will put the top end at 35*.
if there's a little pinging at wide open throttle, then knock it down a degree or two.
if there's a little gurgling at part throttle acceleration or uphills, then dial back the vacuum advance a little.
If you have the original dual point, important will be cam condition and good quality points and condensors. Halifaxhops can prob help on those.
If you have an aftermarket distributor, then you may be able to modify it to get the curve close to shown above. depends on what distributor it is.
