I have one of the older grinds by Hughes that I plan to run. It's not the Whiplash but at the time it was their largest offering. It's like 220 @.050 on a 108. It'll be noticeable, but I'm sure not be what I'd call a rough idle. I don't know what Dave's thinking was with this new line of camshafts. It appears he was trying to do the Erson reverse grind thing. He's about 20 years too late and his grinds are way too small now. For someone whose supposed to be a Mopar expert, I'm not the least bit impressed.
