any way to ID 4Bolt BBC later model
I know early 4 bolts had a 1" plug above the oil filter but later models did away with the 1" plug. I'm guessing when they started with the external oil filters between filter and block?
I found one thats supposedly out of a motorhome and hope it would be 4 bolt but pan is still on it - I know would be best to pull pan and look, was hoping ther would be an external identifier, anyone?
