The cam specs you posted will be better for the turbo ( split duration with higher intake value, larger LSA ). The +5 advance will help off the line but require a bit more tuning work to avoid detonation ( BAD, trust me! ).

As always we are looking forward to the end results!

Same here Mike. I'll take whatever the hemi gods will allow. Thanks for the info on the cam. I figured it would be advantageous for me to let them swap it out. Hopefully it won't be too difficult to tune. With the pcm flash I have, along with fine tuning the smt6, I'm sure they can nail it. I'd hate to have all the new forged bottom end parts in and the motor dropped in and tear something up. I believe the 220 cam was installed at 4* advanced if that makes much difference.

Colt,
If I am not mistaken that cam has a -4* overlap which will definately help with the boost... if it had positive overlap some of the boost will be going out the tailpipe.. I have thought about asking if that particular cam would help over the stock one.... probably be RPM limited without the boost ... Got to be great for your application though.

Curious.... do you have any idea what your final static compression ratio will be??
