I did some playing as well, I have EA 3.0.....
FWIW...
With a custom hydraulic roller using Comp lobes, 236/240, .630/.630, 110/104, it shows an increase of 13 hp and 14 lb-ft at peak. Averages went up 11 hp and 13 lb-ft.
Again, just a simulator, but in reality, I just don't see how taking valve lift away and adding a ton of overlap would help performance at all.
I see a lot of crazy cam recommendations out there. One guy called and bought a cam from me a couple of weeks ago because he had R&R'd the lifters and saw that the lifters were wearing the cam lobes. This had been the 2nd or 3rd cam that he had got from the same company, and each time he had issues with it. However, the common trend was that the grinder had recommended too much duration, way short on lift, WAY tight of LSA for a street car (104 LSA), and then on top of all of that, the spring pressures he had recommended were about 120 lbs seat and like 350 lbs open. The lifters were lofting, valves were bouncing, and everything was just simply jacked up. Supposedly, this cam grinder was a Ford guru as well....
