So I can run 92mm bore with 86mm stroke with just boring the the block and putting in sleeves, on a high revving 11:1 DE motor without issues thus giving me a Engine Displacement of 2.3 and Engine Displacement (CC) of 2286.8. A Tuner in my area had told me no to run 92mm pistons but instead run 90mm but I don't remember why. Any ideas.
