Is the upper plenum the same on 350 vs 305

I'm think of buying a upper plenum for my 1991 Z28 350 TPI Speed density camaro.

I figure for $100 bucks it;s a decent deal to buy a second one that i can mess with and port out, that way i still have a car to drive in the meantime.

So i just wanted to know if there was any difference in the upper plenum in 350 vs 305 or anything cause the part doesn't say what it was from just says it works on 90-91 camaros

thanks for the help,

No difference in any of the parts within a given model year except for the injectors they put in them.
