There are a bunch of manufactures that make 041 like cams, at least 4 and a bunch others have in the past. They all seem to net the same results (modeled) with "very" little difference. I guess that makes sense since they are actually very close or exact copies with a little more lift. I seen a post by UD Harold that indicated that the UD and Vodoo cams were not the same. He indicated that the overall advertised duration and lift was dictated by Lunati, but the lobe was of his design.
I have wondered if that meant the Lunati cam was an improvement in his mind, or was he held to more design constraints at Lunati, which forced him to ramp the lobe up quicker? Was the UD cam a better design with less constraints?
In any event, all seem to fall in the same range of performance as other 041 like cams. The question could be, which is better from the aspect of less valve train wear and tear, idle vacuum, and driveability?
