i read through about 5 posts. and the confusing part to me is, say all i want to do is put as big of a cam as i can go ( without converting). I called summit and they said they dont carry one. it is a 351 W. also cant i bypass all of this by switching to a carb and buying a trans controler? i had a buddy who did some major mods to a 69 351 W and put it in his 95 f-150. The cost was far from cheap so i just want the most cost efficient option. thanks for your replys
