TurboRaider did the cam testing. He may still be around on the 4 x 4 wire.

Oh wow, sorry about that.  My ADHD mind was of course 3 steps ahead and I thought you were TurboRaider.  

I did have a chance to clock in the Monsta-Banshee straight up and take degree measurements at every .050" lift for intake and exhaust.  I plotted the info similar to how Kevin C did.   This may not be as bad as I thought.    Wish I had his data to better overlay the charts.  

All in all,  the Monsta-Banshee cam with the V6 roller rockers has a 121 degree lobe separation and a 119 degree intake centerline (with no adjustment to the cam gear).    The curves fall right on with the measurements Kevin C. took using the stock cam with either the V6 or magna roller rockers.    When plotted out, they don't look too bad. With a little bit of advance (not as much as I was going to do), it may make the cam feasible. I still have a bit of research to do though.

Not the best graph, but enough to visualize this cam.   The top curve is the Monsta Banshee with no advance/retard of the cam gear.   Degrees are in camshaft degrees just like Kevin C's data (on bottom).    exhaust valve on the left

Note that my data was manually obtained by taking degree readings starting at .006" lift and then every .050" lift. No where near as detailed as the profile Kevin C made in the lower curves.

The Monsta Banshee has pretty much the same intake centerline and lobe separation as the stock cam with the 3.0L roller rockers (as expected by the cam cards).

Depending on if the company you chose had a similar "master lobe". Otherwise its $$$$ to have one made. But yes, thats how you map a lobe.

This is great research. I used the rollers years ago and never figured out why they ran the car so badly, I just gave up and put the slip rockers back in and was back in business. I admit not having the patience at the time to deal with all of this!

Elgin cams doesnt grind or regrind cams for the g54. Crower cams will grind a cam to any specs you could want. Also the cam grinder that Tim C. Used for his grinds is Colt Cams located in canada. Spoke with the owner today and a very nice guy.
