Does anyone run a Lunati VooDoo cam, and if so, what do you think? It'd be nice to know what drivetrain/exhaust setup you're using with it as well, and please, please, please, post some video of it idling and revving.
I've got the little Edelbrock cam in my 390 right now, and I'd like a more agressive idle and a bit more power. It's nice to see off the shelf 0.904 lifter cams finally available to us. I've always thought highly of Harold and UltraDyne, knowing that he designed the Voodoo gives me a warm fuzzy. Thanks! |

1969 AMX with Comp XE262 cam (similar to the Voodoo 262, but on 110 LCA). Stock engine except for roller rockers and better valve springs, unknown mufflers and 2" dual exhaust with no crossover. Owner did complain of valvetrain noise. Edited by Greyhounds_AMX - Aug/29/2014 at 9:05pm |

Love the greyhound avatar. We've had a couple ex-racers and have a greyhound/wolfhound cross right now.

Got a Lunati Voodoo in the 390, it's not running yet. I can tell you that Lunati stands behind the parts. First cam arrived and was not straight by just a few thousandths of an inch, enough to cause rotation binding. Called them and they shipped out a replacement immediately. The two cams crossed each others path in shipping. Replacement cam was spot on correct.

I was reading the stats on the 10100704 Voodoo cam and the advertised duration is 276/284 and the @ .050 lift duration is 234/242. By comparison, the Edelbrock RPM cam (#7132) is 310/320 advertised duration and 234/244 @ .050 duration.
The @ .050 duration is almost the same, but the advertised duration on the Voodoo cam is significantly smaller. That is a sign of aggressive cam design, and assymetrical lobe design if memory serves. That's the "more area under the curve" that they refer to. In other words, the voodoo cam is a cutting edge lobe profile compared to the Edelbrock cam. It's almost like a solid cam profile in the raw numbers. I have the 7132 cam and ran it for about a year before going to the solid lift cam. It was VERY stout and I have considered going back to it if I pull this motor for any reason. But I'm really liking the profile of the 10100704 Voodoo cam, so I would very likely consider it. Unlike the Comp Thumper series, it's not about about "the sound" but I think the Voodoo cams are an attempt at REAL performance. FYI, I believe Harold Brookshire has contributed to some of the cam designs of both Comp AND Lunati over the years. |

The assymetric lobe is merely a different shape on each side of the peak of the lobe. It is usually done to open the valve quickly, yet set it down more gently. If you have an aggressive opening ramp, and close the valve just as quickly, your valvetrain could lead a short, hard life. Edited by Sonic Silver - Aug/29/2014 at 5:19pm |

The VooDoo cams are supposed to run a little quieter valvetrain wise than the Comp XE, and build a little more power as they have more duration at 0.200". I really like that the AMC VooDoo grinds are 0.904" lifter specific, and more agressive than the SBC VooDoo cams can be.
