Stop in for a cup of coffee

@71GSSDemon any new progress on the boy’s car?

Just what I tagged you and Matt @Mattax in last night or this AM. So it smokes terribly. It does have 13" of vacuum at idle, but on both ported and manifold vacuum ports. Guessing the throttle blades are too far open. The idle mixtures screws do nothing, even all the way in, runs fine. Again throttle blades open too far and allowing transfer slot fuel? IDK. Thoughts this AM pointed to maybe damaged the valley pan gasket - this could be an internal vacuum leak and the oil vapor/smoke. Also, the vacuum line that runs from the intake to the transmission vacuum modulator is a known source of smoke. If the diaphragm failed, engine vacuum can pull trans fluid (Not Bud Light @memike has a case though) into the intake near #4 cylinder. This could explain the smoke on passenger side. Plan is as follows:

Change carb to the Holley and try
Unplug the transmission vacuum hose – maybe a diaphragm is bad and possibly pulling fluid up???
Pull oil fill cap and see if there is a vacuum vs blow by – this would prove a crankcase vacuum leak
Pull and replace the valley pan
Reassemble and retest
Then if runs correctly, decide if it still needs the converter or return it
