3) The metering blocks are also different between square bore carbs and spread bore carbs BUT the metering blocks interchange between the 650 and 800 spread bore carbs once you change the Jetting and Power Valves.

4) The Dual Bowl Fuel Line is also unique to spreadbore carbs.

5) All of the spread bore carbs use the "Johnson" (a Holley VP's) primary/secondary double pumper linkage design.

Tom, that old carb looks terrible! I think you should just send it to me. Seriously, that's obviously a nice virgin carb. Nice to see one in mint condition. These carb will flat make some power. An 800 spreadbore double pumper and a 455 4-speed works fantastic. Had a 650 on a 389 when I first started driving. It worked great also.
