New to all of this

The 400 is an excellent engine and there are plenty of new parts to go either the mild street version or, my personal favorite, go for the throat version. One of the most used mods for the 400 is to drop in a 440 crank (with remachined journals) and stroke it to 452. With this combo we'll see how good that Ford 9" you're running really is. By the way it is a 9" right.
