The primary and secondary intake lobes have the same profile? And is that total duration? I thought stock was more than that.

470hp from a 350, man that's awesome! Where do I sign up?

Pete,

Where did you say you had the regrinds done, I must have missed it.

I would say that maybe you should sell these, but clearly by the lack of posting in the thread, there would be no interest.

All Durations are @ .050
Yes,both primary and secondary lobes are same.

Stock Intake cams are .214 primary .229 secondary @ .050
Stock Exhaust cams .214 primary .214 secondary @ .050

If you guys are still interested to find out which IH's are better now is the time.
Let me know.
Again i don't think we will see much of a differance,if ported the right way,i could be wrong.
I can use a friends late IH's that i ported,i will do the labor you guys pitch in for dyno and gaskets.

Lee,do you think people will pay $1500 to reground stock cams for 20HP?
But then again we pay $1200 for headers which are worth 20HP.
If there is interest i'll do it.

I woukld like to know how the curves compare, before and after the cam swap........20hp at peak but whats the average across the power band. That might be the selling point.
