Timing set at 12 degrees, Curb Idle at 850, i'm pulling 23-24 inches of vacuum at idle in park. ........when i put it in gear (Reverse or drive) it stalls. checked for vacuum leaks (has all new hoses and plugs etc.)none.... I bumped up the curb idle to 900 RPM same deal....turned up idle mixture same deal... what next....could it be a bad torque converter??? it will sit and idle fine and starts right up every time. Go Fast and Swerve!

The specs you posted sound good. I was thinking we tried the starting fluid b 4 & it didn't help live every 24 hour block of time like it's your last day on earth

What he said , if you have something setup wrong and the lockup clutch is applied it will stall when you put it in gear if your foot is firmly on the brake.

So if something is set up wrong, and the converter is locked up....how would I dis-engage the lock up? (the PATC kit is installed how the instructions said with 44psi and 52 psi witches T'd off the pressure port and I have the on / off toggle in line with the 44psi switch. and the vacuum switch to keyed positive with a fuse) I'm gonna disconnect the vacuum switch and see what it does...

It was a carb problem the whole time. It was a fairly new edlebrock so i had kind of elimanated it from being a problem . Try swapping a different known good carb before you pull the trans. I wish i had. I did take the carb apart and didn't see anything unusual in it , i wish i knew what it's problem was.
