I've spent hours and days at the engine dyno with these new Hemi's. They normally like between 19-21 degree's.
I also read the Mopar Muscle artical. I didn't like the fact that they hogged out the MP intake before testing it. Anyways, I did however test out a factory 5.7 intake, 6.1 SRT8 intake and and an XV intake at the dyno one day. Test's were performed on a 418 stroker with 5.7 heads. The 5.7 and 6.1 intake were pretty much neck and neck. The XV was low on hp/tq throughout. I have one regret is that I didn't spin the XV any higher.
