I’m currently gathering parts for my twin turbo build. After long discussions with very smart people who have been there and done that, I will be going with a 4” stroke. The extra load on the cylinder walls with a 4.25” stroke is not worth it. Don’t worry about the cubic inches, let the turbos make the power.
