I say regular because I am not sure what the different kinds are. I have seen this XE-R modifier and I was wondering what is the difference?

Colonel

The XE lobe is more aggresive (opens the valve at a faster rate because the lobe is steeper) than a standard lobe. And the XE-R is even more aggressive than the XE.

oh okay, thanks.

then what types of lobes do MTI's X1 and the TR230 cam have?

Colonel

X1 = XE-R
Not sure what the TR lobes are called but they're mighty aggressive too.

I think TSP uses XE-R lobes. LS1 Speed will order you a Comp custom using XE-R lobes for $379. If you need help coming up with a cam. PM Shawn at NCP. He goes by 93PONY.

The nice thing about the XE-R lobes, even being as agressive as they are, they are VERY streetable and allow for a steady idle.

I have ridden in a Z06 with a XE-R 232/236 112LSA that was SO much smoother idling that my old 226/232 112LSA from a few years back.

I guess it is all in the shape of the lobe.

The pictures at the bottom of this page helped me out a bit.

You may have already seen them or are already familiar with the information, but hopefully it will be of some use.

Those are some very helful illustrations. Kinda makes me want a solid roller cam in my streetcar.
