Swap the V6 then drive a V8 car and you'll return to your V6 disappointed. A mild 250-300hp 318 would be fun, get decent mileage, be cheaper to swap in, as reliable and have more torque, which is what makes them "funner". Find a 5.2 mag, swap the pan, pickup and intake and enjoy. Newer engine swaps become far more complicated and most loose interest before its completed as they're pioneering new ground on how to retrofit all the systems required to run it and the transmission.
