OK What the....??????

Nephew had a 383 stroker in a '69 Camaro, and it was a monster. Don't see the deal on inches. Several manufacturers have produced same inch motors. Ford and Chevy 302's, and all three had 400 inch motors, come to mind. When you start boring and stroking, you're libel to come up with anything. First one I remember was punching a 283 Chevy 60 over to 292, (Ford engine at the time) I have one sitting in my shop right now, 40 over, and if I calculate correctly, that make it a 289, another Ford number.
