Jon, the high rate of lift is true. Mopars have .904 diameter (i think!)
lifters, while Shivvy's have a smaller diameter lifter. This allows a
higer rate of lift. Most cams are ground on chevy lobes, so most cam
companies give the Mopars the smaller lobe sizes. Hughes doesn't though.
They have Mopar specific camshafts ground for them. There's a lot more to
it, gets hard for me to explain it, though...I don't think any of that made
sense, btw, but hey, I tried!
