Casting number question
I just bought a tubular upper and lower intake for my 5.0. I cant find information on the lower anywhere. I dont know what its off of. The casting number on the lower is RF-F4ZE followed by 9K461-BC. I have been going nuts now trying to find the info. Any help would be appreciated. Thanks
