Most likely it is a 223. The casting number is on the front corner on the drivers side. You could cross reference the number to be sure.
Ditto! You would be hard pressed to find a 262 in a '59 F-100 but if someone added it later it's possable. Carb looks like Motorcraft of a later engine, 223s mostly had Holleys.
yeah , youre right, the carb is a 64 carb, dont know what its doing on my motor, but i want to know if maybe the whole engine was a 64? I'm having a hard time finding any info on the carb, because i dont know exactly what it is..
