Hi Chris
The last engine I had built was 5.4L made 420 RWH with the same cams I am using in the new Cammer. This time looking for 420 to 430 RWH the cams fell over at 7400 rpm in the last motor but the new heads have had a lot more work done to them and flow better. The Cammer is oversquare will have a lighter rotating mass and better flowing heads so the dyno will tell the story. I will rev the engine to the point when the cams stop making power hopefully past my wish list shift point 7500rpm.
