==Ford Thunderbolt== When the subject of cold air induction comes up, the first car some may think of is the 1964 Ford Fairlane Thunderbolt. Dearborn Steel Tubing (known as DST) purpose built these cars for NHRA Super Stock drag racing for Ford. The engines that they used were the (very underrated) 425 HP, 427 cid high riser side oiler. To feed cold air to a engine of this size required large (~6" diameter) tubing connected to a large aluminum air plenum box atop the dual 4 barrel carbs. The large air box required a bulge in the hood, and to get cold air from the frontal area to the large intake box, the designers used the area where the inner headlights normally resided for the intake. They added grills to keep out large debris, and ran the ducting up to the intake box (seen below). The result was the iconic look of the Ford Thunderbolt.
