Hey guys, got this air cleaner with my 71 sport fury 383 4BBl but not sure if it’s original ( I doubt it actually) . And what’s that big hole next to the snorkel for ? Kinda figuring out if I want to/ can use it with my rebuilt engine . If somebody got an original used one for sale let me know please . don’t actually know either if it should be dual snorkel ?! Any help is much appreciated!
