ew years ago I and my brother bought a lot of engine parts at a garage sale. One of them is a Holley, with two fuel bowls but only one pump. It has vacum secondaries.
Then I lost that Holley in my garage (didnīt need at that time) but found it again today.
I would like to know what carb I have (CFM) because I am starting to build a 400 cid small block chevy and need a bigger carburator than my current Holley 600 cfm.
I wrote down all the numbers I could find but they are:
On the bottom of the carb there is the number 3205
On the primary fuel bowl is the number 12R-10554B
On a plastic thing beside the choke is the number 34R-10880B
On the primary pump is the number 34R-2178B
Also I found the number 172 and the number 173 on the vacum secondaries.
This carb was on a 351 windsor and I hope my sbc will not reject it
