4th Gen Motors in 3rd Gens

Are the 4th gen motor and tranny setups able to fit into 3rd gens? I saw a site were a guy was going to put a 4th gen Ram Air motor into his IROCZ convertable.

Is this possible and how much (if any) modifications are there?

Can the 4th 6speed transmissions bolt up to 3rd gen 350s?

I don't know about an ls1( I know it can be done, but not how hard it is to do) The lt1 swap isn't all that hard. It is in my opinion a cheaper option than building a comparable L98 tpi motor.
