I have a 4brrl carb that was ontop a 65 300 sbb. Now some have said its for a 300 and others have said its for a 340 originally. I dont know but have the casting numbers on the first picture. Carb looks good and not rusty. Was stored inside. The carb has some damage on top where the long rod screws in that hold the air cleaner down. The threads are not damaged becasue i was able to take the rod out. Will trade for a 800cfm qjet or A oil pan for a 430. Or an oil pickuptube plus 10$. Shipping not included. Coming from 92371 CA.
