The rods we use allow us to offset grind the crank. We can stroke like the one we did for Tony, leave it stock or destroke it. Custom pistons must be used either way (except for stock stroke length, we use stock pin height). It was free displacement, so might as well taken it- but, when your doing big monster snails and going for big power like Tony is attempting destroking it is another option to slow down piston speed (slightly). The next issue I see you running into is hydraulic lifters/valve float and valvetrain control if your gonna try to zing it to the moon. Good luck, we'll be following you!
