Further testing showed it wanted 42-44* initial @ idle, but didnt chance it cause it was 87 octane.
Do you mean 42-44 total at 3500 rpm or 12-14 initial at idle?
Dolp! From beer belly memory(as 69Fbody says) with other cars in between. And why before and after notes are so important...make a note to self to take better notes... 16-18 initial with vacuum can disconnected(which is set to give another 10-12). 42-44 total. 400 block/455 crank/87cc E-hds/Crower RA-IV/1.65 roller rkrs.
Another prob found was the "used" Demon 850 needle/seats were altered, and would'nt adjust properly, Replaced them with std holley's, and went down five jet sizes since then. Idles better, but havent been able to test yet.
