We had a ford inline 300 I wanted to rebuild for a guy's rat rod, the shop I used since I didn't have the equipment to do it my self. had to shave .008" off the deck #2&#3 bores were .010" off center in the opposite directions Took a while to figure that one out the only thing we could determine was the engine had previously bored to .030" Ordinarily the block would have been scrap in my book but the guy wanted to go max overbore and a 4.375" stroker crank I think he wound up with somewhere in the neighborhood of 336 to 338 CI range Not a high rev'er but had torque for days
