Just off the cuff, the 470 is making a little better hp/cube, which makes sense with the longer duration lobe. It would be a fun test to dyno it with 2 different cams with the same lobes, with the only difference being 108 vs. 112 LSA, and then check it again at the track to see if it impacts ET any. The narrowish LSA seems to make sense with what Trick Flow was targeting, stock block builds where you're trying to keep the engine speed down for longevity and keep the hydraulic rollers out of instability, provided you can live with the degredation in idle quality and low speed drivability.
