2-Part Cooling Question

[Shyguy]

When you put the shroud on you need to make sure that the fan fits at least half way into the opening.

I bought a '75 that had a different engine in it and the fan is outside the shroud. The engine runs cool enough when the truck is moving, but when it is setting still and running it starts to get pretty warm.

I put a set of of electric fans with a shroud from Summit on a '92 with a 454 and for some reason which I could not figure out the stock clutch fan kept it cooler.

If you go with electric fans you will need a higher output alternator.

Changing your crossmember and/or the position of your motor could create an issue where your fan ends up. Also, long water pump vs. short water pump. If your fan is too far from the radiator, it might not pull enough air to keep the temps down.
