v6 and v8 cameros are very different cars. You're going to need to change a lot of stuff from the bell housing, radiator, motor mounts, maybe some suspension parts for the extra weight, etc... I would consider getting a front clip out of a v8 camero, drop in your v8, bolt up your transmission with a new bellhousing, and get an alignment. Why settle for a 305 when you could have a 350?
