Shovelhead oil filter - unreal
I went to change the oil in my custom shovel head that I'm unsure of the year of the engine. All I know is that the filter was attached to my BDL primary kit. Upon learning that every auto parts store really only sells a three-quarter inch thread for any of their filters, this filter has a half inch thread and I can't find it anywhere. Does anybody have any ideas as to what kind of oil filter I should be using?
Edit: it's a 5/8" thread, thanks to the wonderful guys at Napa!
