I couldn't find more than three or four items that were worthy to be on the list. How about superchargers, turbochargers, overdrive performance manual transmissions, auto trans shift kits, MII suspension kits, the positraction rear axle, roller camshafts, nitrous injection? I'd add more, but it ain't worth the effort. That list looked like an advertisement. Another reason I haven't bought Hot Rod magazine in the last 10 years or so.
