I'm fairly certain I know my own answer, but when you swap out a 305 for a 350, the exhaust manifolds on the 305 can be reused for the correct?

Yeah, but you'll seriously choke it.

S.

so... If my car is running really rough and such right now, is there a possibility of the manifolds being a problem, or should it still be running decent at least, perhaps with a little loss in power?

I highly doubt thats the problem.. You should check things with a scantool.
