360 Magnum Build w/ V Belt Configuration Question

I do have some pictures. The reason for the 45* inlet is the engine is quite a bit higher than the radiator cap, so that really helped an issue I had with air pockets and overheating.

Don't pay attention to the rat's nest of wiring. I was in the middle of wiring the truck.

As far as the thermostat housing is concerned (in the rats nest pic :)), do you remember what you bought that for? I know the thermostat style is a little different compared to the older LA style.
