I pluged you info into the Cam quest . I went with 11.5.1 C/R But your engine is higher . And found a cam that was a near match to yours . This is what it came up with 569.8 HP at 6000 RPM and 574.9 ft lbs of Torque at 4500 RPM . I think the heads you are running will hold back some of this HP . I would say that engine may go 525 HP and 510 ft lbs of Torque . It is a hard one to call
