It's trial and error. If it's a stock points style ignition start with factory settings. If it's an aftermarket electronic ignition, you'll need to know how much vacuum, mechanical or electronic advance there is. Most street engines work best with around 32 to 36 degrees total advance. So you use a timing light to set basic timing at 10 to 14 degrees BTDC, and find out how much vaccum, mechanical or electronic advance there is by 4500 RPM ( it's usually best to have all the advance in by 3600 RPM for a street or strip car). Then reset idle speed and use a stopwatch to test 0 - 60 MPH times and go with what setting gives you the fastest time without pinging. Maybe even a couple more degrees retarded for street use on pump gas ( you can always bump it up a few degrees at the track or when using octane boosters).
you should have timming marks on the front engine block. if you see it you will need a timming light to set it very cheap to buy. if you do not see any timming marks and you have a distributer losen it a little but with the car running. now with the car running turn the distruber left or right until you hear and feel the car idle high. once you feel it idle low go back up until it idle high and keep it there and tighten the distruber back. turn the car off and try starting it back up. it should start right on time with the correct timming and idle. good luck
timming marks on cams face each other 3 and 9 o clock crank mark at about 6 o clock mark in cover and sump auto adjuster arrow should be in v mark to set this requires turning water pump by loosening water pump bolts slightly be warned some times this causes pump o ring seal to leak if turning.
