Yes, I used it.
It's odd though, because with a 106 ICL and a 112 lobe seperation the cam says its ground with a 6 degree advance.
is that 6 camshaft degrees or 6 crankshaft degrees?
The walace calculator does not say which to use.
I think it's crankshaft degrees because the if I use a degree wheel it's hooked to the crankshaft.
So, 106/112 means 6 degrees (at crankshaft) advanced? That means 3 degrees advance ground into cam in cam degrees, right?
if so I doubled 6 in my calculator which is wrong. It's only 6 degrees which works with the numbers you gave me.
Thank you for your help!!!

I just played around with the Jeep Strokers calculator and I now see where you get the 6* advanced from.
Hmm, funny way of doing it.
Anyway, they state that it's crankshaft degrees, and I didn't pay any further attention.
You can use that calculator again, but this time type in 57 in the IVC block (bottom left), which bypasses the LSA etc blocks.
The DCR won't change when you change the altitude figure, but the DCR at altitude will, which is correct.
I found your Lunati cam, but they don't show the cam timings.
Not to worry, 57* is the actual IVC number.
When you fit your cam, use a degree wheel to verify the cam timing events. Imperative that you do this.
You're very welcome.
