Circa 1976. Orange County Dragway. '61 Falcon coupe ("Humpin' Henry"). 300 six, Clifford manifold/header (custom), Roush "Cleveland" head (351C heads carved up and welded back together for a 6). 10.60s over 125.
That six has had more "goodies" made for it and won more races than any other straight-6 I know of. Remarkable performance potential, surpassing the Chevy and Dodge offerings of the era.
Don't discount Clifford Per4fromance. While much of their stuff is "dated", it still WORKS!
Cool idea, the 6.
