Wait, wait, wait... now I'm no expert, but I always hear about offset grinding to get 0.3" out of the stroke... but wouldn't it add 0.3" to the throw, not the stroke? Think about it... the center line is 0.3" further from the main center line than it was, adding 0.3" to the throw, or 0.6" to the stroke.... So wouldn't you essentially be able to get about a 4.45" stroke from a 460 crank, and all the way up to a 4.9" stroke from an A514 crank? (In other words a 4.75" stroke because I hear that's the biggest you can go.) So with under $400 for the crank and however much the offset grinding will cost you could have a 4.75" crank for 567 cubes without boring the engine at all... Maybe I'm wrong here, but that would be pretty cool. Not to mention, get yourself some 6.8" rods then get pistons designed for a BBC with 6.7" rods (BBCs have a 10.2" tall deck height, BBFs have 10.3", the 6.7 pistons with 6.8 rods fill the gap), then you'd have your whole rotating assembly from mostly shelf parts.. sounds like a good deal to me.
