Mike is correct. The Twin Six was set up like two independent V6 engines linked at the crank. Separate valve covers, intakes, etc. Each V6 used a single 2bbl carb. The engine redlined at something like 2400 rpm, but the torque would change the rotation of the earth. Apparently it offered diesel torque, low HP, and abysmal gas mileage.
