Somewhere here there is a thread where we began to discuss this. Using a 228/248 crank the stroke is 3 13/16. with a bore of 3 15/16 that gives you 279 ci. To do this with stock height pistons .095 has to be milled either from the head or the deck. This is from California Bill's book and it was his favorite street combo. Somewhere I read that this could turn 7,500 rpm. That seems like a lot. I used to shift my 270 at 5,500 regularly and it would turn 6,000 but it lost power before it got there. I don't know how or why it would go that high but it did. It would only do it in first and second gears when I was running 4.11s. I have thought of doing his to a 302 for a supercharged engine. Just so 5,000 to 5,500 would be in it's comfort zone. Of course we know that these are not high winding engines but 5,500 is not that much.
