I'm having a little trouble with a holley carb... Someone gave me this carb a while ago, they had no idea what it came off of... I don't think it's an o.e. carb for anything because it has a manual choke and 2 fuel feeds.. I posted a bunch of pics in my gallery... Thanks in advance for your help..

Looks like an older double pumper. Check here for your numbers to see if you come up with anything... http://www.mortec.com/carbs.htm

The one shown looks exactly like yours with the exception of the auto choke.

 

Great that was exactly what I was looking for , the exploded view looks like a vacuum secondary unit but other than that it's exactly the same... now I just need to find an adapter to put it on a spreadbore intake... Thanks again for the help

 

It looks like it might be a 4010 750 cfm

 

Here is the link for the 4010.

well, it's actually a 4013 but it's the same as the 4010 and the 4011 for the rebuild kit at least.... I noticed the picture of the 4010 shows the vacuum secondaries even though the part number that holley shows is for a mechanical... from what I found on holley's website it's a universal 750 cfm double pumper with a standard square bore mount.. no info as to how old it could be... I don't think it's too old because it uses torx screws to hold everything together versus regular slotted screws like the real old ones.... I think I'm going to bolt it on and see how well it works (IF it works) before I go get a rebuild kit or anything...
