Radiator and cooling options

A Thinner, wider radiator will cool better by itself. Remember, Mopar installed these engines from the factory, so they will cool, if done properly.

Unfortunately, the opening in the radiator support is only so wide, so a wider radiator doesn't gain me much. So short of cutting it open more (which I really don't want to do), it appears my only option is to go stock 22" width radiator with a short mechanical fan so I can fit a shroud in.

I could go with a stock radiator, or even a newer design aluminum, but since I am running a 70's 400 in it, the water pump housing has the inlet on the passenger side instead of the driver side, which was standard on pre-70 something motors. It seems that everything I look at for radiators, that are called out as being for a big block 67-69 Barracuda, have the upper hose on the passenger side and the lower hose on the driver side.

Guess I could look through the water pump housings I have and swap it out to a driver side inlet and just put a stock design 67-69 radiator back into it with a mechanical fan and shroud. Just wanted to see what others on here did.

Thanks!
