In a build like this, retarding the cam that far is really not what we want. Not to mention I don't believe it's how Harold designed these lobes to run. They actually like more advance than what the cam card suggests.
Paul can explain it better, but the idea of moving the cam forward and having the intake lobe higher during overlap is to allow hot gasses to escape before the compression stroke, which helps with detonation. Since this is a pump gas engine with iron heads and 9.98:1 compression I wanted to follow this theory to the letter. It worked very well on my stock RAIII engine.
Plus these lobes from Paul's experience, already carry the power out petty far and don't fall off much in the upper rpm range, even with the cams moved forward this far. It'll hit the dyno soon and we'll see
