It really depends on where the outlet is on the bottom of the radiator. The factory big block A-Bodies have it all the way to the drivers side as it will go, the 340 radiators are a couple inches from the end, but the oil filter makes it tough to get the big block hose to fit...
I am using a aftermarket radiator made to fit a 71 Cuda with stock hose locations on the radiator ( lower outlet is about 1 inch inboard from the lower drivers side corner) and you are right the lower hose is a tight fit but it does fit
