383 hp Identification

It has HP stamped on the lower right of the identification pad.
HP motors would have 4 bbl carb, 10 to 1 pistons, windage tray,hotter cam, stiffer valve springs, 6 quart oil pan,double row timing chain,mine has a HV oil pump but not sure they all came that way.
Bottom line is any 383 can be made an HP as the blocks are all the same.
Edit: Added picture of my 383 HP Stamp.

here’s another example of a 383hp. 1968. It’s hard to see.. blow it up a bit and you can. D 383. 3. 6 in middle then in lower right corner the HP.
I should also say that pad is on the front corner, passenger side of motor as in post 3 from beepbeep. The b motor. 383/400
