Unusually high advanced timing
Hey guys I have an 87 full size with a 305 5.0 and the timing likes to be unusually high it won't hardly run at 8 degrees advanced and alright at 12 advanced and it runes great at about 16 or even more I don't know for sure because it's way more advaced than my teeth on the measurement thing I've tried different timing light and coil and wires and still the same result is this ok to run it this advanced or should I be conceded and if so anybody know what is causing it?

you do have the vacuum advance removed from the distributor & plugged, right?
i had one of my SB's in one of my pick-ups, that ran best @ 18* timing, so i left it there. mind you, it wasn't exactly stock, but i never had an issue with it.

It doesn't have a vacume advance I don't think it's HEI and it started doing this when I replaced my distributor with a oem one from checker is there somekind of adjustment I need to do to it before it goes in or are they plug and play? Oh and it might be possible that the plig going from my controle module to the coil might be switched around the clip was so dry it broke off a long time ago and i might have switched it around is that what you mean by hooked up wrong? If not I don't think there is anyonther way to hook it up it seems pretty straight forward
