I'm trying to order the correct cap for my radiator.  It has the 2 mount studs on the bottom.  But is currently side mounted. Large radiator cap outside dimensions 2 3/4 inch inner filler neck 2 1/8 inches.

  Looks like the original CJ2-A radiator that’s been modified for your Chevy V8.

I could be mistaken, but the choices that fit are are either 4 pound or 7 pound?

Yes, it appears to be M38, which is the same as the desert cooling option.

im trying to figure this out

Part # 810391 is a 4lb for bottom mount radiators 2 7/8 necks !

Is this the one that I need?

Is a 4lb cap suitable for my 283 and the stock radiator?

This has a lot of small modifications that I dont like but -as this is my 1st one - I just want to enjoy it for what it is. It's not ORIGINAL - but at least I have one.
