73 Mach 1 Carb advice

Hey Guys. I have a 1973 Mach 1 351C-4v and 4spd toploader. The engine has pertronix ignitor/coil, upgraded cam (i know its upgraded but no idea what it is) and edelbrock intake. Exhaust is stock manifolds with h-pipe and dual 50 series flowmaster.

I currently have a Holley 80457-5 carb (not sure they make it anymore but this looks similar to Holley Performance Products 600 CFM Four Barrel Street Carburetor*0-80457S). Its starting to leak a bit so thought I would try my hand at rebuilding a carb. I also have a Holley 1850-2 on the shelf which I had on the car prior to purchasing the 80457.

I bought the 80457 new and traded for the 1850 when I needed a carb on a budget so I have no idea where it came from.

The specs on the carbs look pretty identical from what I can find, just wondering if anyone had any thoughts on if one would be better than the other in some way?

Thanks for listening,
