I have on my hands a weird holley carb. while im running an edelbrock 650 AVS thunder series on my Elco (Darcy) i found in the back of my dad's shed an old holley that i can't identify. i kind of want to put a holley on instead of my edelbrock because i've always heard you have to adjust Holley less than edelbrock and they get better overall gas mileage.
The holley has R 6910 B stamped into the main body on the top right side of where the choke would be. everything i have found says that it should be an 800 cfm big block double pumper with an electric choke. but like i said it lacks a choke and there is no secondary accelerator pump. it does however have vacuum secondary.
also P-80 is stamped on the left side by the throttle linkage and R-81 is stamped behind the vacuum secondary on the left. my best guess is that it could be an old 6910 that someone refitted to go on a small block. (it was on my buddy's 81 chevy blazer before he gave it to my dad, which had a 350 in it.)
any thoughts or help would be apprecieated!
