Can you guys give me the LOW DOWN between the GM/Chevy PU & Dodge

The 75 W-300 he’s almost got complete for his dad is a real tank, though... high swirl 91 model 318 with a performer intake and carb, 7 blade clutch fan and had water pump, 4 core radiator, 435/205 divorced drive, modern Dana 70s front and rear, 4.88 gears, suregrip rear, Detroit locker front, dually, soon to be flat bed. Double plated the entire frame! I can jump up and down on the rear frame rails and only the tires give a little, the springs don’t even budge... he didn’t even bother putting the overload springs back on it yet, came with 11 leaf factory primary springs. I’ll post some pictures of it when I see him again. When you look up truck in a dictionary, there should just be a picture of it instead of an actual definition.
