They are both Series 2 so odds are good. What are you trying to do?

Wait, so you're taking the L67 supercharger off of the Impala and putting it on the non-supercharged L36 in the Bonneville?

The engine I bought came out of a Bonneville and I want to put it in my Impala but I wasn't sure if it would work if I switched the intake out so I can use the supercharger

No, you can't just swap over the supercharger.

You are better off swapping out the whole engine.

Though, there have been a few people that have swapped over the heads, intake manifold, fueling system, */C etc, but they had to do a lot of ACTIVE custom tuning. Which means, scan/log then tune. Scan/log tune.

Yeah, what Mike said.

. . . and even if you did swap all of that, it'* questionable how long it would last that way. The non-supercharged engine runs a higher compression ratio and weaker connecting rods.

Good point. Depending on how happy the transmission is, it'd be a race to see which dies first.
