Looking for stock slant performance #'s D150

Member " my68 barracuda" has an 83 d150 that he did a frame off resto on, it is a /6, although no longer stock. I know somewhere he posted details on the build, I don't know if it was here or over at the /6 site or both.
Over there he's "Dad truck" as his dad had originally bought this 83 new and now he has it. It's a short bed 2wd.
I know I've seen extensive details on this truck--- besides the ones I've gotten from him directly face to face--- weights, engine build details, Dyno results and more. And I've seen his record keeping for myself when I've been over at his garage. I definitely need to do better in that department. It's a short bed , /6 with 833 od, I believe it was originally a 1bbl with 3.21 out back
Now among other improvements it's a super 6 and (I forgot which) either 3.73 or 3.91 out back.
He don't chime in on the forums near as much as he used to (have no idea if he's lurking) but if anyone I know would have the stock numbers on an 80s truck with a/6 "before", it would be him.
