If it's going in a Jeep then a 305 is all you need and that is a great deal if they are both working. Check out Edelbrocks new carb they have just for jeeps and off roading, I hear it's good. I am not sure which one it is but it's a newer one and if you go on their site or Summit then you will probably find it and know which one I am talking about.
Good luck!
