If you run the 3 x1 manifold the linkage makes all carbs operate together, the better way is to have the truck cruise on the center and have the outer ones come in only when you are on the mat ,or 2/3 throttle ... a cam with somewhere between 195-200 duration at .050 would be a good choice , with that small of an engine any bigger would hurt gas milage .comp has a cam part number 61-113-4 that I think would work well ..... the dyno tests on inliners is a good test , just not sure how small of a cam they used and if they pulled the engine down to a point where the normal 6 does most of it's cruising ..... my video on the 261 with a 213@ .050 made more torque below 2400rpm , and we just never thought to pull it any lower to see what it really made as far as max torque .. but it was more than likely around 350 ft lbs , thanks to a 4.220 stroke and a 3.900 bore ......... I will have to see if I can find the photos of the bottom end ,it was h beam rods with a custom piston and a 2" crankpin....
