I know this is an old thread but !!!!!!!!!!!!!STOP!!!!!!!!!!!!!! Don't to it!!!!!!!! If you don't care about performance you can do so many things to a 455 that will make it streetable with good mileage. If you don't want to do the carb work yourself take it to someone who will. Quad's are great efficient carbs that can be tuned to be street/race ready.
IMO if your worried about gas mileage, your driving the wrong car. You can save a ton of money by just changing the cam and getting a good tuned carb and maybe (if needed) swapping the gears. the will cost you much less money and save you a lot of time. Plus, a T/A without a 455 is like a pool without water; it's not even worth it.
