Hughes cam?

Absolutely no argument. A faster ramp certainly makes more power. It also is harder on the valve train. They beat the valves open and slam them closed in comparison to slower, lazier ramps, so lots of times, they are noisier, even with hydraulic lifters. If it's a total 100% street car, "I" kinda want a slower, lazier ramp. Much easier on the valve train and less noisy. But you're right. If you're lookin for every bit of power, a modern grind is the way to go.

Ok, but just keep in mind that the Mopar grinds being used were designed around the .904 lifter used by Mopar.
I don’t recall hearing of valve train failures on the performance Mopar engines, the same Mopar engines that would have had the faster ramp due to the .904 lifter that Mopar designed and specified.
The way I see it, Mopar designed in a larger lifter for a reason. To get a steeper ramp. They would have also designed valve trains to handle it.
And besides, it’s ramp speed, not opening and closing rates.
