"POWER NATION" slant six build

I expect that in typical driver cars, people notice low rpm torque more than max HP. Few people drive around screaming their engines in low gears (except rice-burner tuners). The same show also recently did a Ford 6 cyl, and they got great torque out of it (>300 ft-lbf). They used a unique Offenhauser "dual port" intake. I have one for my Newport (383 V-8 ) and want to see what improved mileage and torque I get. Too bad they never made one for the slant.
