====Tunnel-Port 302==== The 302 "Tunnel-Port" engine was envisioned as the motor that would bring Ford a third Trans-Am Championship title in 1968. Starting with a 1967 GT40 block, Ford fitted cylinder heads with a design based on their NASCAR 427 heads. The intake ports were straight, instead of snaking around the push rods, while the push rods went through the center of the ports (thus the name "Tunnel-Port"). This configuration also enabled larger valves to be used. The 302 tunnel-port motor was topped off with an aluminum dual quad intake. Shelby [[dynamometer]] runs showed the engine was capable of producing {{cvt|440|β|450|hp|kW|0}}, and of operating in a very high rpm band (8000+).
