engine swap?

I have an 87 trans am with a 305 4bbl, what parts would I all need to swap in a 350? can I use the exhaust maniflods and rad form the 305?

Everything from the 305 will fit the 350.externally they are nearly identical

so everything will bolt up, is there anything I will have to change? what about the fan, somone told me the 350 needs 2 fans.

im guessing u have an electric fan as long as you have a large rad in good cond. it should be fine. i had a three core rad in my firebird after i did the swap to a 350 and had mech fan. when it comes down to the exhaust it really depends on the heads u use but usually its pretty universal.
