Hi. Can anyone tell me what this is behind the overflow tank on the cutlass. I’m continuing to put together my car, but when it was disassembled a few years ago that part got lost. Thank you

Looks like a MAP sensor.

yes a map sensor you need it if still using the computer controlled carb system or throttle body injection

Manifold Differential Pressure sensor for Olds V8 cars with CCC.

It's usually mistaken for a MAP sensor, but it works differently. Cannot mix and match those. Although it appears you won't need it if you're putting in an LS. So I wouldn't worry about it.
