What you're going to want to do to the engine depends on what does it come with from Summit.
If it were me....I'd make sure it was balanced, get a set of good aluminum heads, install a hyd. roller cam, aluminum intake and 750 carb.
Change the ignition and dist. too.
Add headers and you should have something that fills your needs.
