Holley carb id

hi i have a holley double pumper carb manual and i cant find any info on it the numbers on the choke tower reads 4777-5 and 3256 and on the side reads 8050b and i wanna know what rebuild kit i would need and what cfm it is i looked on the holley main site and for some reason it skips the 4777-5..

It's a 4150, 650cfm. Renew kit is part number 37-485. Trick Kit is part number 37-933.

See Below

Glenn
