1st through 4th isn't terrible even with the 5.0 and whatever gears it has. Just 5th sucks. Hopefully the 350 a few addons and a tune fixes that

What do you mean by lip on the throttle body?
I don't really understand why you have a concern with your 5th gear, its overdrive, its not supposed to be a fun gear or anything, just overdrive for better MPG.
