Identify this flathead carb

Hi all,

My good budy just picked up this 8BA manifold with a peculiar looking carb on it. Possibly a big truck carb? Anyone know?

 

1949-1951 Merc

 

Rochester AA carb.

 

This..Holley model 885FF 2bbl, R493-R637-R638-R652-R679-R690

 

Yeppers thats a merc carb....My Merc runs fantastic with mine.

 

Mercury came with a larger carb than Ford, and a 4 bolt intake. A Rochester 2GC off a Chev V8 will bolt on. This used to be a common low buck hop up. Rochester carb and Merc manifold fits on a flathead Ford. The local dirt track stock cars used them back in the sixties.

 

Still is. Got one on my '42 Merc powered AV8!
