Which way out

Which side the inlet to the water pump housing is on would depend on the year motor, or at least the year of the water pump housing. The original housing inlets in 67-69 cars was on the left side. They moved to the right side in the early 70's (don't remember the exact year). My 67 Barracuda has a 77 400 in it, and the lower hose inlet to the water pump housing is on the right side.

I like it over there as there isn't as much over there to interfere with it.
My engine came out of a 66 charger and my 68 cuda had a 340 from the factory. The 383 didn't have the housing on it when I bought it. And my cuda didn't have a radiator. So I'm trying to figure out which side housing to buy. I too thought there would be less clutter on the right side. I know 440 source has some. I guess you could get the radiator to come out on either side.
