Not a chance on it acting like a duration increase of 6+*. More like 2-3* max. I would sure like to see the source that claims double that as I could use a good laugh!

The only problem I have is, that I'm now done with DOD, and hate the fact that the non DOD lobes have less lift. So, now I wanna cam. Probly go this route http://www.performancetrucks.net/for...d.php?t=438267
Look at his torque curve!

Very impressive!

William,

I have no idea what that particular nipple is for. I put a rubber cover over mine about 2 years ago. If someone knows what that nipple is, we'd all like to know.

Damn, when you read this at first....lol...

Don't feel bad William.. I've got the same thing as well. At heavy and WOT is when mine happends.. Like you say, sorta sounds like a whistle... Gotta be a leak of some sort. Not sure if it's at the manifold, the DP/header weld, or something else....

Sounds like a couple of us have the same problem with some searching to do....

I'd just ditch my gold race rockers, and run non quick lifts! Can you imagine what that set up would do with our Heads, pp tb, LS6 intake, with roller rockers and our headers! We already have a 3000+ stall and with some 3.29's or 3.69's

Put the car up on a rack, running, and listen to every exhaust connection with a stethoscope? Bothers me too, but I love the power!

I'm getting concerned now. I don't have a TBS. Was hoping it was a bad weld etc. but with multiple people having the same problem doesn't look good.

DP's pic:

William,...this is perfectly normal, its how the gasket is made. IDK why.

When I installed my TB spacer I noticed this is how the gasket is made and the gasket that came with it would had probaly caused a leak! It didn't have that nipple.

Here's mine Will!
