Awesome Bill! Just what I wanted to know too....especially the 0.006" values so that we can determine the DCR.

Anyone know the specs?
The basic spec @ 0.050" is 211°/230° with the total lift after rocker ratio 0.591"

Cam sensor trigger is not on the cam... I suppose if you use an early LS2 cam sprocket and front cover/sensor assembly with an adaptor harness you could... along with a set of 1.8 rockers to maintain the lift specs.

Once you get the specs, just have it ground on a traditional ls1 cam blank. Problem solved

How will this cam sound in a motor with smaller displacement (346)

There is way more to grinding a cam then just getting the right "specs". There are things like opening and closing ramps and valve acceleration rates that vary dramatically from cam company to cam company. GM lobes much gentler then aftermarket lobes, since they ahve to pass stringent durability tests. THe aftermarket is not concerned about that, they make parts for more power.

Are you saying once they get the specs from the cam doctor they can't tell how steep the ramps are on the lobes? If that's the case then what is the purpose of using it. I would imagine all they would need to grind a new cam would be the "specs" from the cam doctor.

Are you trying to say the cam companys are only going to use their lobes?

If you read the 2nd post, maybe you would understand that when I say specs they are a little more specific than just saying 211/230 or just throwing #'s out there.
