I don't know of anybody running a Mast cam around here, but that doesn't mean that there isn't anybody. I'm curious what their cam lobes would be comparable to? They say that they're designed in house using proprietary software. I like the specs for a nice daily driver, but I'd definitely recommend a mild torque converter to help get that heavy CC moving....something between 2600-3k (closer to 3k IMO), and a 3.73 gear at the least. If it were me, I'd probably go with a 3k converter and 4.10's, and a big azz TruCool 40k trans cooler. Curious, do you have VVT, and if so, would you delete it or run Mast's phaser restrictor?

 

yes i do have vvt and i would deleate it

 

I have heard nothing but great things about mast.....just not around here.

 

Is Mast a sponsor on the truck side here? If not, I can tell you why not to buy from them. If so, I'll keep my mouth shut.

 

Theyre not a sponsor over here.

 

If I was going to buy something from Mast, it would only be because of the VVT stuff. If you are going to get rid of a good technology, you might as well go with a different company.
