Fuel pump: Probably, but you may need to replumb some fuel lines. Inlet/outlet orientation varies a lot on the pumps.
Carb: Can you? Yes. Should you? Probably not.
The mounting bolt spacing will be wrong and you’ll have to file or grind the throttle body to mount it up. It will also not be well-calibrated for your engine. The desirable versions of the 216 carbs tend to be more available and more affordable than the 235 ones. I’d recommend sourcing the right one.
