Issues with a rebuilt 360

Had to change power valve in quick fuel to a 6.5 as it was a 2 digit number can’t remember what it was exactly but engine over fueling now runs drives idles in gear (727)
Ignition timing becomes an issue with higher lift cams be careful total advance no more than 38 degrees at 3000 or BAD things will happen. May need to run off mechanical in disc and crank to get it to idle properly no vacuum advance. So crank will be probably in the high teens
