Factory Big Block Trucks has its own shroud.
Small block trucks has one for factory A/C trucks, one without A/C, one for 4 Wheel drive.
Chevy in line 6 cyl have just a metal topper shroud over the fan blades.
GMC V6 have a full shroud as all the other trucks.

The GMC 6 cyl shroud & one of the small block shrouds may be the same.
