Wow, I did not know you could use a 4.75" stroke. On a tall deck, when you use a 4.5" stroke do you use the offset pistons with standard rod length? Just curious..

With a 4.5" stroke, you can either use a 6.7 rod and a 1.25 compression height piston or you can use a 6.635 rod and a 1.27 piston. If you use a 4.625 or 4.75 stroke crank, you have to use a 6.535 rod.
You can get pistons with just about any comp. height that you can dream of.
