In case anyone was wondering, there are Jim Wolf Technology VK45DE camshafts that are available.

"Titan V8 S-2 Camshafts now in stock!
Date:8/16/2007
JWT thanks Chris Forsberg for his help in the test and development of our VK56 S2 Camshafts. Chris's VK56 powered 350Z was the perfect test bed for testing the new S2 Camshafts. S2 Cams are an excellent choice for a Titan Pre-runner or any VK56 powered Nissan that needs to run hard to the redline (and beyond with JWT Valve Springs and Reflash). Dyno testing has shown Increases of 30+WHP in the Titan truck. PART# AVK56-N00S2 (S2 Camshafts are also now available for VK45 powered Nissans.)"
256deg .430"lift (compare to stock at 232deg. .346"lift) 219.5deg@.050"lift

I'm not sure what the difference is between the VK56DE camshafts and the VK45DE camshaft, but they are there.
I would have done this a while ago if it wasn't for the difficult install. A few local tuners told me 20 hours of labor or roughly $1,900.
