model of my carb?
hey guys i bought a holley DP but cant tell if what the model number is or the CFM rating,i think its the 4777 650 dp
the choke tower has been milled off and all the choke assembly is gone too,heres the numbers i have been able to find..
172 primary throttle blades
173 secondary blades
it apears to be 11170 with a 5 below the 7,on the metering block,primary
11166 with a 3 under the first 6 on the secondary metering block
on the airhorn,righthand side,right next to where the choke tower would be is the following,6R5534B
any ideas?
