Sorry I guess I missed this , when did you post it ??
I assume you want to stay with a hyd cam , solids seem to make a lot more power but require adjustable rockers , 273 rockers work great for this .for a Hyd cam I would look at the Voodoo cams from Lunati , duration control the RPM range of the cam & you have to be careful with this if you are not going to change the torque converter .
What I would do is choose a cam with an 1800 - 5800 powerband & use a 2200 stall converter to match . This should work well with the stock engine . the 60403 meets this , if you are not changing the converter the 60402 is what I would use
