Thats about right. Its definetly a BBD 1-1/4 and since it has an external bowl vent that uses a hose on it that went either to the charcoal canister or the valve cover breather it should be from about a 71 to a mid 70 vehicle. I also remember the 318's going to the Holley 2 venturi carb that sorta looked like the BBD. My 83 Rancharger with the 318 had the Holley carb. One thing I hated was even when I had the carb number and the parts stores would say they cant find the number. That happened more then once over the years. Good luck as I would think any kit for a 71 or 72 BBD 1-1/4 should work. Ron
