3810 carb???

[RichSchmidt]

I am still helping a frined sell off all the old stock that he has laying around his garage{He has been buying and hording chevy stuff for over 40 years}and he came across a new in the wrapper"manufacturer rebuilt" holley 3810 carb.I had to look at it 10 times because I kept thinking that it was a 3310 with a bunch of wrong parts on it or something.It has a GM number on it I think,since there is a long number above the list number and it starts with 390,which sounds like a GM part number.I plan on listing this ting on Ebay,and I was wondering if there is anything I should be looking at on this carb.I shows as a stock replacment highpo 327 carb,but I dont know much more then that.Is this a desirable piece?Thanks in advance.
