I called Peter today, I'm gonna going to drive up and have a chat to him mid next week. I'll prob swing by Lewis engines, early nexty week and have a chat to them aswell. Its always good to get a second opinion or another set of idea's. I know about the differences in the cam profiles, hence I'm trying to decide what is the best way to go now... I dont want to be change my mind half way, though 1 build and decide on the other.
