im going to be coming across some money this winter and im kicking around the idea of not only rebuilding my 351w but punching it out to a 408 stroker. but i have a few questions i have gt40 heads that i was going to put on it will they work or are they going to be too restrictive? also what kit is the best kit an "eagle kit" or a "Scat kit" in the long run this isnt going to be a track car or anything crazy its going to be for pulling my projects around. and its going to be carbed and i want to double check that a 600cfm carb will do the trick. thanks... chuck
