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.
