Lo all!

Where would be a recommended (best) source to order A COMPLETE REBUILD (or, renew) KIT for a Holley 850 Double Pumper?

I have spent some time searching the inter web (here on C-C.com, Year1, Summit, etc) only to realize I left all my Holley cross reference and number charts, in the car which is locked up in a buddys garage til Monday.

No doubt about it, my Google-foo is very weak these days  :violin:

Anyhoo, the car now has a 440Mag in it (out if a 70 GTX) and, since I also need some valve cover hold down washers, hopefully I can get them from wherever I am able to find the correct carb rebuild kit for the Holley 850 double pumper ...

Thanks in advance, have a safe and awesome weekend!!!!!!!   :drunk:

Evening?  I tried the Holley website to identify which rebuild kit I needed; however; as you point out, I need to figure out where I putbthen#s I trapped years ago, just for this situation (alas, I think I left em in the car which is in a family run garage that is closed until Monday morning (I was really hoping to get the darn kit ordered today or this weekend :-/

I did not try the Holley website to purchase ...

Have a safe weekend !!!

bowl gaskets, metering plate gaskets, needles  are all pretty much interchangeable, where you get variables are accelerator pump diaphragms (15, 30 or 50cc) & body to baseplate gaskets...

If your sure it's a double pumper the Holley 37-485 covers 99% of them made in the last 20 years... The older ones had allot more variables...

Thanks Wild (& 70), really appreciate the help; its a pretty noob question I know (right up there with, which way do I turn the handle to make the window go down, etc, ha-ha! 😳) but, I CANNOT WAIT to get back to a place and time where I can sit down at the computer and dig through all my files or do inter web searches for an hour or two at a time, the way I used to (wah-wah!  😭

I dropped the car off to a buddy (I can trust) at his family run shop and I never dreamed itd still be there 3 weeks now for some pretty basic stuff but, when I stopped by Friday it was apparent they are getting swamped, to the point the person ordering parts, etc. just cant keep up.  Anyway, I gotta get my car back, cruise in weather is here (it was 74^F in the Smokies foothills last couple days!!!) so I figured, Heck LET ME get on the stick and get these parts ordered and get back out on the highway! :burnout:  (Judas Priest playing in the background  :stirpot:

I am almost positive the 850 double pumper is less than 20 years old so, I may just roll the dice and order the 37-485 kit.

Any suggestions on where to order it from, in case the local Advanced or OReillys etc. doesnt have it?

I wasnt having much luck at Year1 or Summits websites (found some Holley renew kits but, nothing specifying fir 850 double pumper)

Man, I did not realize how not having that car in my own garage was gonna give me the heebie-jeebies and the joneses (but, 3 weeks, cmon man!!!)

Thanks again, fellas!

Most double pumpers are 4150 series carbs.... And manual choke is virtually a given.... Try Summit or Jegs....
