What type of camshaft are you currently using?
Camshaft Brand: Reed Part Number: 540 TA282R TA292R 110A3
Specs: 282-292 advertised .660 valve lift, .375 lobe lift 251-260 @ .050 110 centerline, 104 intake, 116 exhaust

Considering the current peformance of your vehicle, do you need:
More Low Speed Torque? No More RPM? Yes
Is Idling Speed Important? No Is Emissions Compliance
Important? No
ADDITIONAL INFORMATION:
Would like a easy on parts lobe with about 10-15 degrees more duration. Existing motor is only 4.0 stroke, stroker motor will have more cubes and compression. Would like to stay with pump gas

With your current setup I really don't think going larger on the cam will gain you much in ET. Your compression is a little low to run much more duration. We could start bleeding off to much cylinder pressure and lossing power. If you would still like to go about 10 degrees bigger as you suggested I have included the part number and grind number below.

Part number = 33-000-9
Grind number = 4374/4378R109
This will put your duration @ .050 to 260int/268ext with a .697 lift on a 109 LSA (I shortend the LSA a touch to build a little extra cylinder pressure)
