Need help identifying Holley carb
Need help identifying Holley carb A friend of mine gave me a 4 barrel holley that he says was either a 600 or 650 double pumper. I wanted to find the exact model of the carb but have failed. I found the following numbers on the carb
List-6708-1 0199 . I also see 7445, 8672, GR 4950
Any ideas of what carb this could be?

A double pumper is I guess a nick name for a Holley with mechanical secondaries.
Plus if you open the throttle by hand and all four open, it's a mechanical secondary carb.
Plus looking at the pics, yes it is mech sec.
Now you know three ways on ID'ing one.

thanx for the help. I cleaned the carb last night. I will be doing a motor swap this weekend and slapping on the carb. Then depending on how the carb behaves I will order the rebuild kit.

Good luck!
That carb was built specifically for Chrysler by Holley for the 1970-72 C Bodies. (Polara, Monaco,, Imperial). Not the easiest to find parts for, but not impossible.

1) Used on the 70-72 Chrysler Imperial 440 engines with automatic transmissions hence the Chrysler kick down linkage shown in these pictures.
2)Only Tech data that Holley had can be found here. (It's a PDF file with float levels, choke settings, etc. No CMF, jetting, or Venturi diameter data.)
Have some friends in the local MOPAR club looking for data, but they've come up empty-handed too.
