It is not 41 pickup, 6 or 8 cylinder. I don't think it is 41 pickup at all. It looks to be a bolt in on a frame that has boxed front rails. Note the upper flanges sticking out. As far as I can tell, that would not fit either of my 41 pickups.

Can't say what it is, but can say what it isn't.

You're not doing yourself any favours by posting the pictures in a very difficult to see orientation.
