(NOTE: the book shows slightly different numbers, they upgraded the specs since last printing) I've heard several times that circle track cams make excellent drag cams due to massive toque from the bottom end up thru the lights.
JR109H (the H for hardened) 260/270/106+4 from Custom Cams Inc.
Recommended range = 3200 rpm thru 7200 rpm
Duration @ .050 = I 260, E 270
Lift w/ 1.5 rockers = I .561, E .578
Lobe lift = I .343, E .385
Lobe speration 106*
Lash (hot) = I .020, E .022
Standard SBC firing order
The cam costs $200, and the Crower lifters with oiling hole in face (EDM)are $164
This sounds like a cam kit that may work for your application when time to change it out again...?

The Bullit cam i have is jus a little bigger and it was a killer in the 406 i was running. I got talked into changing to a roller and alcohol toliet bowl and only picked up 1/10= $1,000.00 plus dollars
