Drag Pak heads and camshaft questions - 05/14/17 09:39 PM
Can anybody tell me what heads the new 426 Drag Paks use and what they flow? Also, the only spec for the cam I found was .675 lift, but what about real duration and lobe separation numbers?

David Barton told me the Drag Pack heads are cnc'ed but it hardly scrapes the walls. I really dont ask flow numbers because it seems the only guys on the same page are the 4 or so of us on this board all have basically the exact same numbers
If you dont need Drag Pack heads than it maybe just cheaper to get Thiteks

What I did find on cams was for an earlier year Drag Pak that had a legal Bullet cam for that car. The lift isn't has high as the latest one, but the cam was 270 at .050 intake, 275 exhaust.
I don't own anything Gen III, but am still interested in what goes into them.

Getting Cam specs on competitive Drag Pack motors would be like asking for the recipe for Coke. Never gonna get it.

I didn't ask for the specs of the fastest class-legal Drag Pak's cam. Everyone that bought a new 2016 426 Drag Pak got the same cam from the factory. Any idea what those specs are?

Even that type has a few ingredients now a days, depends on it's cut, each cartel has their own special blend....the 70s are definitely not coming back...pure simple but moderate profit snow gone the way of bell bottoms

What are you guys seeing with your own heads, and how much work to get those numbers?

I think they are limited to .675 at the valve.

Stock @.600
Eagles and 6.1 heads 300cfm
Apaches around 335cfm
The 3-4-5 numbers are really awesome on the g3s. Eagles hit 300 at .5

What about the exhaust flow on the Eagles? I understand the exhaust is only 55% of the intake? I'll have my newly acquired Eagles on the flow bench next week, but always interested in what others have seen.
