I have a '73 z/28. Pretty simple components: 350, TH400, Holly 750. If I step on the brakes and decelerate quickly, the engine will die. I can immediately knock it into neutral and start the engine afterwards. Anyone experienced this one before or have any input?
I'd also check for your kickdown cable. Your situation is common on automatics, hence why they put in the kickdown cables. I've only worked on a 350 but would suggest something might be binding near your carb
