Anyone know how to ID a carb with the choke milled off? I think that is what is going on here, cant find any number except GR 3752 b on the top of the main body. Primary metering block has 10569, and secondary has 11166. I am thinking they are around 800 or 850's, but cant find any of those #'s in the holley book.
Trying to establish a starting point for tuning purposes
pull the base plate, on one the "ears" there should be a number cast in. On the carbs up to the mid to late 70s its the list number of the carb plus a 0 at the end.
that is assuming no one has replaced the base plate.( that will atleast give you the CFM of the carb.)
