Mike,the carb the Bathtubs ended up using back in the day were the 421 SD NASCAR 3443 carbs,except for throttle arm and jetting the 3705 Max Wedge carbs are perfect.Again,if Brad had the arms avil there is a carb place in NJ that could put them on if John could not be talked into doing them.Also as you know the 750 E carbs race well just not so good on the street IMO.The carbs on my 63 engine are cloned 3705s,I also have a set of 3443s.Tom
