2 and 3 pass radiators

did alot of reading when i did this upgrade,thought that cooling system psi vs heat exchange vs radiator surface area that the 2 pass would be best for my car. yes both the inlet and outlet are on the pass side of the car. this is a stock 74 new yorker 440 that i rebuilt in 94. schumacker 1 3/4 ? try ys, when i had 2in cppas and power brakes,boiled the brake fluid,went to alum master cyl with heat shield and remover the booster,went with smaller headers no problems since. running 6lbs of boost,
