I spoke with Dave on Thursday and we discussed some final options. we are waiting to hear back from the the shop with the heads.
It seems we are a little limited on the lift and duration due to the VVT.
I will let you know what the final numbers are when I hear from Dave.

I spoke with Dave on Thursday and we discussed some final options. we are waiting to hear back from the the shop with the heads. It seems we are a little limited on the lift and duration due to the VVT. I will let you know what the final numbers are when I hear from Dave. VVT... So you've got me curious now. We are replacing the blown 5.3L Vortec in my wifes SAAB. It has Displacement on Demand or DOD as GM called it. That particular 5.3 had an LQ9 camshaft option, which omits the high tech gadgetry that is variable valve timing and displacement control. Anyway, in doing so you couldn't just tune the ECM like I have to omit my MDS, you have to flash the unit to start from scratch and not recognize all the parameters and sensor affiliated with the system. Granted VVT systems are producing gobs of horsepower from straight cam and head packages alone, but is omitting this an option in the new 5.7? Not that I own one, mine is an 06, but should I acquire something newer with the VVT and look for performance. I'd rather have a solid cam and head package that is straight duration and stroke... I guess if you don't mind sharing, let me know what options you've learned about and were you required to keep the VVT? Otherwise I'd have suggested the infamous FRI Motorsports, or www.modernwarfareperformance.com as they are called now. Like so many others, my new cam is going to be an FRI Sparrow... ooh, I might just have to order it soon. My tastebuds are watering. Lookin forward to the results! |

Thanks for the question.
The VVT is something you can turn off, But, as you said it helps produce some great numbers.
I am not willing to give up the benefits of the VVT throughout the full rpm range.
The Cam we will use is the most aggressive design to work with VVT
If I was building from the bottom up it may be something to fore-go.
But for now the technology is just to good to give up.

Sounds great! I can't say I disagree with keeping the new techno goodies. That's what makes the 5.0 in the Mustang so stinking powerful is its cam and head design with VVT. Ooofda, a HEMI with it is a dandy idea for sure.
I know nothing about the shop your working with. But perhaps when the time is right, I know what I want, but I want the right shop to do the work. Maybe these guys will get my car for a week or two.
Again, keep us posted.

Angle: 116 My goodness! Those are very impressive numbers! I wonder what other supporting mods were done to the test car that was being dyno'd? Cant wait to hear it and see it tear down the track "HHP TESTING: With our in-house test car, a 2009 5.7L VVT 6-Speed Challenger with stock engine, Kooks 1.75" Long Tube Headers, Corsa Cat-Back, AFE CAI and 180 Thermostat, we tested this new camshaft for Comp Cams and we were extremely surprised by the results. Tuning the VVT HEMI with a big camshaft was a challenge but we are extremely happy with the results and the new lopey idle this car has. Take a look at the pics above or watch the video below to learn more about what this new camshaft and HHP can do for you." Straight from the website. Nice choice on the Cam. $880... holy ish that's a pricey piece. But with that VVT those cams are not simple to build. I can't wait to see and hear a new HEMI with the VVT and a cam. Comparing base cars... I think he's about to unleash the real beast inside that HEMI. WOW!!! Makes me want a new cam, really, really, really, really... get it, really bad! |

I have to say I am excited as well. This will be one of the first applications of this cam, as very few have even been shipped. The Tune and new dyno is being done now with Ported heads. So these numbers are BEFORE any head work!! They are going to provide the tune with the ported heads once they are done so we can have a place to start. Looks like I will be waiting untill after MATS to get started. Attachments:

Impressive numbers to say the least! I'm going to have to look into this one of these days. What kind of porting are you having done, full port job or port matching?

Great Specs, sounds like this is the cam to have. Got me looking around for a cam now, thinking I am going with a more aggressive cam than the SRT MAX cam ;D Down sound this cam needs extensive tuning, its that big |

It was a custom job done by a guy that worked for Mclaren.
The specs are similar to the Arrington phase 4 heads.
Should be plenty of gain for what we are doing.
I will post a picture.
We will be changing out the springs and retainers maybe adding a cage.

I keep looking at those FRI cams... to bad without the VVT of the newer HEMI we won't see such massive gains. But hey... something is better than nothing!!!  So she said... Oooh... and you've got to see these: Also... so she said. |
