How much is this stuff worth?

Arright yall. Whilst on a junkyard date with my fiancé, I stumbled across a 79 Ford van that was full of 60s and 70s Dodge parts. I got out with this:

Not sure if it's visible but there is a number on there. I have a full set of 8 of these. I believe they are forged, and appear to be unused. Judging that from the total lack of wear on the skirts. I imagine they could be used if they were cleaned up. Most of the engine parts were big block stuff, and I believe these are too. Any clue what they are and if they are worth anything?
The forged +.03 pistons may clean up. The critical areas are the ring grooves and the pin bores. If those are clean they should be usable.
Number is barely legible in this pic, but I can get a better one if needed. Obviously a Carter AFB, but I really wonder what it was for and if it has any value.


I appreciate any help with this!
The carb is an AVS, if nothing else the 3 step rods and caps should be saved. What is the number on the left front pad?
