Carb Question

[Cruizer67]

I have been chasing down a Carb for my car (1984 5.0 GT) for a little while I have the original carb that came with the car but it has some issues I recently went to a swap meet and found a couple of other 4180 carbs the original is 50151 what I have is a 50260 from what I can tell they are very similar .. any one know what the differences would be? physically the look identical but was wondering if anyone has any insight

thanks

1961 thru 1070 mustang and some gm cars. I just googled it.
It could be anywhere from 470 cfm to like 530 cfm you can find more info, I didn't get into it any farther. If you can find more numbers hit up carbs unlimited's web page.
