Thanks Jeff, yes it was built at ET Performance and Cary and John built it. It is trick for sure and I wasn`t sure how well it would work on the engine. ET also worked on the Heads a lot also. We used mine as a start for the new ones with improvments. Someone like yourself could work on the new ones and pick them up, they are not maxed out. 7.20`s would be cool but frist things frist, hope to have it in the car by the weekend.
