Some help please

Okay so I know this says 79 through 95 but I have a 71 Mach 1 with a 302 carbureted engine in it and I need some help

Okay so first off I have a Elderbrock (or however you spell it ) carburetor 700 CFM's and I just replace the gasket between the intake and the carburetor cause it was bad. Now it's running like ***** when you put it in gear when it's in park or neutral it runs fine but when he put it in reverse or drive it starts running like ***** and stalls out also sometimes it's really hard this start after it's been running (after stalls out)because I think the choke is staying open and it's doing something I don't know but it's hard to start so I need some help with this anybody have an idea about anything

I would say it's the timing. I adjusted mine to 14 degrees BTC and it started running like **** when I'd put it in gear but it'd run fine in neutral or park. So I adjusted the throttle plate when in gear with the e brake on, just so it wouldn't choke out. It runs perfectly fine now.
