"Talk about building or hopping up a 305 and guys will generally shun you, or even boldly accuse you of being a fool. You'll hear, "Why mess with that junk motor? You're wasting your time." Wouldn't it be nice to lay waste on their stuff instead, with a few discrete bolt-ons? How about a bolt-on package that will add 150 crank hp, and still pull a good 13 in-hg of manifold vacuum at 850 rpm? And what if all the stuff comes in cheaper than what it would take to build the average high performance 350 short-block, and all the parts will transfer over to a larger engine and work great if you ever decide go bigger?"
