Do you plan to have a/c on your ride? If you do, and I see you are from Shreveport, don't even consider a 350. A 56 radiator will cool a 350 if in good shape and no a/c but not with it. Since you've said performance is not a factor the 305 will run 30 degrees cooler and allow a/c with no cooling system upgrade expenses. The 305 will cruise the speed limit effortlessly, get a tad better mileage, and idle all day in 100 degree weather with the a/c on. It will take 3 or 4 more seconds to get from zero to sixty in case you have something very critical to do with those 3 or 4 seconds.
