Called Delk. I believe they will be building me a motor. Talked to heath the tech. He was knowledgeable and answered all my questions. My goal is a 4.6 2v with 320-350 rwhp. We are talking about specifics soon and should have a plan developed soon. We know my goal naturally aspirated is going to be fun and if we ever want to throw on a power adder, the engine will hold up.
