Every blower company seems to have a different idea of what makes a "blower" cam. The only commonality I see is using 112 or 114 lsa. That's usually accompanied by the comments of decreasing overlap. Yet there are much bigger so called blower cams ground on 114 but have a lot of overlap due to their increased duration. Also, it's often recommended to have more exhaust duration. Which makes sense to me. BDS grinds theirs on a 110. The old man from Dyers said he really likes the 280, 474 Mopar Performance cam. It seems there is no real perfect cam. Its about your usage. Just like naturally aspirated.
