trever1t had great results without headers on his 5.3 and a similiar combo. I am going to use manifolds with my 370 and T67.

The Gt2-3 cam will be fine. Bigger is not always better.

The maggie will run out of breath on a 6.0 with full bolt ons. On the dyno, I went from 8.5 psi until about 4500rpm where it went down to about 6. I made 545rwhp.

With JBA ceramic coated shorty's that is....now I have AS&M longtubes and still have the GT2-3, it's a great DD cam in my rig (5.3 w/112) and behaves very nicely.

If I had a little bigger engine...

GT11 looks pretty darn interesting

Would longtubes make much difference in low end torque vs manifolds with the Radix?
I'm not well learned in cam-speak. Would that GT-11 be better for me than the GT2-3?
