6.7 cam?

[txag09]

Zach, I have been searching on what would be an ideal cam for my needs and was wondering what you would recommend? My truck is a daily drive, play toy and I tow with it. I currently have smarty, 90hp nozzles, arson jr. BOD intake horn, 3.5" boost tube, E.D. S469 T4 flange, 6 speed hand shaker. I do not have a rpm increase tune . Also would you recommend HD valve springs as well?

With the size of your turbo, I would definitely run the springs. Im sure your boost is over 45-50 psi so it is important to keep them from floating and reversion(when your exhaust valve is blown open by drive pressure.

I have a 6.7l in my 05 and I have found the 181/210 to be a great cam for daily driving and towing. I had a 66/71/16 non gated that it spooled almost instantly with a very similar setup that you have. With a little tuning, a cam and springs, it would be much better towing than it currently is. Goodluck with your build, and thank you for considering one of our cams.

I was looking at your website reading on the cams and came across this. "Use the 181/210 cut on a 105.5LSA for best efficiency and the 181/210 on a 107 LSA for better spool for racing with larger turbo chargers." Should I go with the 107 LSA to help spool my larger turbo or the 105.5LSA? What is the difference in these two since they are bother 181/210's? So for all the questions zack. I have made my mind up on one of your cams just want to make sure I get the best one for me.
