I have 69 with a 350/350 HP. The motor has just been rebuilt and I am having a problems with slight missing problems. I have done the following
1. Reset the timing to 8 BTD Center
2. Readjusted the lifters to 1 turn after snug
3. set the dwell to 30 degrees
4. rechecked the firing order
5. plugs, wires, cap, coil, points are new
6. there is 5-10 inches of vacume at an idle(OK??) 30 inches at higher RPMS
I think I have tracked down the problem to the Carb. The Carb by numbers is from a 1973 engine. In 68 through 70 they had a Hot Slot in the Manifold that helped warm up the carb with exhaust gases. I reinstalled the 73 carb when I rebuilt it with a 69 gasket at the manifold.
My question is, will the 73 carb by pass the exhaust gases to the intake? Is this why the engine runs poorly?
Any Sugestions Thanks
