The list number is 4780. The air-horn has been removed so I am not sure if it had a dash number after it or not. I found this through someone else's suggestion:
4780 800 (F)72,(R)76 6.5,8.5 4150
4780-1 800 (F)70,(R)76 6.5,8.5 4150
4780-2 800 (F)70,(R)85 6.5 4150
4780-3 800 (F)71,(R)85 6.5 4150
4780-4 800 (F)71,(R)85 6.5 4150
I will pull the bowls off again tomorrow to see what is in there.
Thanks,
Joe
Get the List # and I can check my Holley book.
The List # will be on the air horn if it has not been removed.
