This would be my reccomendation: Lunati 60400LK
Advertised Duration (Int/Exh): 250/256
Duration @ .050 (Int/Exh): 208/213
Gross Valve Lift (Int/Exh): .454/.454
LSA/ICL: 112/108
Valve Lash (Int/Exh): Hyd/Hyd
RPM Range: idle-5000
Includes: Cam Kit

I've used Crane, Comp and Lunati. I'm very impressed with Lunati cams. You could go the next size up to the 60401LK:

Hydraulic. Best mild performance cam. Works excellent in fuel injection applications with performance chip. Makes approximately 19 vacuum at idle. Great for performance oriented marine applications and heavy towing applications. Perfect Street Rod cam. Has slightly noticeable idle.
Advertised Duration (Int/Exh): 256/262
Duration @ .050 (Int/Exh): 213/220
Gross Valve Lift (Int/Exh): .454/.475
LSA/ICL: 112/108
Valve Lash (Int/Exh): Hyd/Hyd
RPM Range: 1000-5500
Includes: Cam Kit

The cam above is what I'm using in my truck with a .040 over 360. Pulls right from the bottom but starts hauling *** around 2200 rpm and pulls hard past 5K. Might be too much for a stock converter, stock compression 318 (I'm running 10.2 to 1).

Overcamming sucks. Nothing worse than having to plant both feet on the brake pedal at a stoplight and wishing you had a third foot to blip the thottle to keep it running.
