Have a 1956 Mercury Custom w/a 312 V8 Y Blk engine and 4B carb that stalls whenever placed in D or R. Problem started after overheating and being left stranded. Since then the heads have been done and all respective gasket replaced. 4B Holley has been replaced with a new Edelbrock 1403 w/elec choke. New distributor core, rotor cap and wires. Vacuum test on engine shows no leaks. Been advised that locking torque converter was a problem but only after the 80's, so it's been ruled out, yet problem persists and we can't figure it out. Any thoughts, recommendations? Seriously need help!
