I am in the midst of having a 408 built, it is the 6.0L iron block out of an escalade, the bottom end is going to be a callies dragonslayer crank, lunati rods, lunati pistons, and the hellfire rings since it will be a nitrous motor aswell (300+ shot)


my question is this... i have the MS3 cam and the PRC Stage 2.5 5.3L cylinder heads from texas speed in my old motor, along with LS6 intake... is this heads/cam combo going to work well with the 408 im having built? compression im hoping will be right around 12.0:1, just safe enough for 93 octane, but there will be a racefuel tune aswell for the track.


i need some opinions on wether i should get a larger cam for the larger motor, or stick with what I have? anybody have any experience with this setup on a 408?

 

Sell the ms3 and buy the Texas giant. The heads and intake should be fine.

 

where is this cam located?

 

he texas giant is form tsp but go with a nitrous cam if your spraying a 300+ shot. talk to some sponsors or predator or patrick g on here and they will send you in the right direction more than anyone else

 

Car will be more motor then anything else, nitrous for insurance.

 

Texas Giant is a good cam for a 408.

But you could always do like transamfreak01 said and ask patrick g, he knows his ****.
