If the crank companies would make one that was not a $1500 piece more people would run them, but the 4.00" is the standard and that the way it goes. I would build more of them, but after you factor in the custom pistons and cost of the crank it puts it out of the budget for most people.
Did you see the videos Jim posted with it in the car? Made the hair stand up on the back of my neck!
