Engine Stalls when placed into Gear
Good Evening Folks,
I am looking for some advice as I am stumped. I have just preformed a rebuild on the top end of my motor, new heads, new fuel pump, rebuilt the carb and adjusted idle perfectly, adjusting the timing, etc etc...
Took the car out for a drive and she preformed beautifully! Came home and parked it.
4 Hours after I wanted to take it out for a drive. The engine was cooled down and I started the car with 1 turn of the key and she idled up to 1600rmp.....perfect! I let it warm up till the choke kicked off and threw her into Drive only for the engine to stall out in a second.
I thought it was a fluke so I started it again in park, let it idle for a bit at 1500rpm till it was steady under 200 on the temp and through the car into drive again.....STALLED AGAIN!
I tried this a few times only to have the same result. The 4th time I gave it gas to keep running and drove down the street but she ran like a bag of ****...
Pulled in the drive way popped the hood and no plug wires are off everything looks good with the carb. Put a vacuum gauge on and didn't see any worry about leaks.
Could I have done something to the Torque Converter? Did my timing **** up, I havnt checked yet as it runs so good in Park or Neutral.
Any idea folks? I have a giant C3 paper weight right now....

In gear idle was adjusted to 750rpm. It was perfect the first time I took it out for a run. Now it just stalls out putting it under any load.

Let me provide some additional information
1978 Corvette

All parts are still original except for what is listed above.
I was reading up on the TH350 installed on this car and it does not have the lockup converter

you said in gear idle was adjusted to 750 rpm. What rpm is it registering in park or neutral once the fast idle has come off? You want that 700 or so rpm to be when the car is in park or neutral.
