You are going to need a decent gear with that setup especially if the car has any weight to it. Probably need at least 4.10 with a decent size tire of 28 inches tall. I would make sure you get a good fuel pump and that carb might need to be worked on a little to work on those heads, depending on how everything flows. Just remember everything needs to work together and be matched to maximize performance.
