I thought I had read somewhere that the truck intake was actually the best stock one for power.
If the engine doesn't have MDS it will be pre 06 if it's a truck engine.

The 6.1 intake is by far the best stock intake for power.
If it is MDS I will be switching out those lifters when I swap the cam.
It'll be interesting in seeing your dyno results between the 2 intakes. I dyno'd a 418 stroker using an 05 the truck intake and SRT8 6.1 intake. Even with the port mismatch both those intakes preformed almost identical to the point when I overlayed the 2 graphs I couldn't tell which was which.
