If you ever contemplate a rebuild of that engine. There was a fellow that converts the original blocks to pressure oiling etc. Price was not too bad back then. Then again you probably know far more about these engines than myself. Quite a few ford pinto engines got installed at one time. Or at least a few if I remember.

I will always remember that with the head off I could apply pressure just with my hands to each side of the block and visually see the bore change size. Litterly millions of guiys got their hands dirty on the model a and model t cars with no forum support back then.
