What is the small threaded hole for in the Shelby 427FE remote
oil filter adapter? This is the portion that bolts to the block. There are two large 1/2npt holes and then one??? 3/8npt hole?? I think it is 3/8" Maybe someone can confirm or correct me if i am wrong.
Thanks
There is a picture of the adapter on the shelby engine site. I hope its ok to post this link.
