Good news. Found a local machine shop to do the DAWG mod.
Interestingly, they had a 3.4 DOHC for sale...[This message has been edited by lou_dias (edited 11-12-2013).]

Is that a "lift rule" cam? The tips of those lobes look horrible

Thats kinda what Will was asking, are you in a "lift limited" class?
Those are also known as...."stock eliminator lobes," "cheater lobes," or "dwell nose cams." Old school for sure. If valve lift is not limited in your class, why in the world are you running something like that? I'm sure you have the rest of the valvetrain figured out. Just curious.[This message has been edited by sleevePAPA (edited 11-14-2013).]

No, I'm not on a limited lift class. This cam has the same valve lift on the cam on the car now, .480. With this design I can have the lift and keep that lift as long as possible. This is an experimental set up for my 2.8 that if it works, it will end up on my big valve 3.4 but with more duration.
And yes, I have the rest of parts; springs, lifters & retainers that go with it as a kit.

This is the benefit of a roller cam. It can get to max lift sooner with less friction on the valve train so it gets to maintain max lift longer.[This message has been edited by lou_dias (edited 11-24-2013).]

Interested to see how that works out considering how abusive it will be on the valve train, lol. Time to open up your own thread? I hate to keep high-jacking this thread but I do have a couple more questions.

In ports that are not flow limited at high lift, the max lift can be greater.

I'll rephrase my statement to "spend more time near max lift". Higher or lower lift has nothing to do with it.
