Default Old 850 holleys

Have 2 850 cfm holleys that I could not get to work on my motor...briefly went through them but didn't spend a ton of time on them and just bought new ones...They are what they are nothing special and they did work for awhile but had idling surge issues on my blower motor but other than that they did work well. I did drill holes in the throttle blades to assist in the idleing issue as you can see. I took them apart to rejet them and ran them once more and pull them. You will get whats pictured but I would plan on rebuilds and jets/power valves

450 shipped for the pair OBO...not really sure what they're worth so open to real offers

About how old are they? how much play is in the throttle shafts and linkage arms?

I don't know how old they are...I bought them on here as ready to run and they were far from it...I went through them briefly just to use them and did what I could to make them run but they surged bad on my blower motor. That being said I'm sure someone who knows more than me can make them work perfect. As for the play in the shafts...I didn't notice excessive play but wasn't really looking for it either...if you're interested I can investigate that further and let you know?

I checked the shafts and to me they don't feel excessively worn but I guess that could be subjective...compared to my new ones they might be slightly looser but not much
