Everyone is different and has different needs. Engine builders should listen to what their customer wants, how the car/truck is being used etc in order to make the best judgement on what the customer would need. Many customers come to use with what they think they want because everyone told them it was "cool" or bigger is better- not always the case and typically they are wrong. We have quick educational session, outline a suggestion and let the customer make the decision on what will work for them. Engine builders (if they arent doing their own machining) should already have a machine shop they deal with, you the customer shouldnt have to worry about that. Just my two cents.
