Not Ranked

My experience with period-correct muscle car engines is that they were pretty much all overrated. I've watched many 442 W30s, Ram Air 455 Pontiacs, 427 and 454 Chevies and a couple of 427 FE-powered Cobra replicas struggle to produce over 300 HP at the wheels. My old Cobra ran 118 in the quarter at a total race weight of a little over 2700 pounds, which doesn't compute to anything like 500+ flywheel HP.
