(http://file://C:/DOCUME%7E1/Owner/LOCALS%7E1/Temp/moz-screenshot-1.jpg)Stan, this is what's in the FSM

I know it doesn't say anything about lift though. If you don't mind waiting for a little while, I'll donate the one in Chaz, after I have the "Mr. 6Pak" grind one installed (http://www.moparfins.com/forum/smileys/smiley2.gif) (it's the '69 1/2 440 6V cam with a lobe profile better suited for an Torqueflite equipped car

Looking in my old Mopar Engines book, I would guess lift would be around .430", based on a '67 383 equipped A-body listing.  It mentions that a 2v B engine and low-po 440 would have a 256 degree duration cam, as well.

From my 68 FSM;
383/440 except "Power Pack"
Intake valve duration 256,Exhaust 260
Intake lift .425" Exhaust lift .435".
The "Power Pack " or TNT motor has the following specs;
Intake duration 268,exhaust 284
Intake valve lift .450" exhaust .458" at a 46 degree overlap and 115 centerline
I am running the RV cam which is in between the two.Great torque response,smooth idle and still pulls hard! Good cam if you are running lots of acsessories and need vacuum.
Mopar P4286675 260/260 duration with .430/.430 lift.34 degree overlap and 113 centerline.Very effecient cam.It is part of my recipe for getting 16 MPG in my 440.
Any time you upgrade the cam,I would recommend upgrading the torque convertor to match it up.
I would recommend a 166K (2250-2350 stall) convertor.
If I am babbling on too much,just tell me to shut up...
