The Comp Cams 260H would be a nice cam for that. Big low and mid range torque as well as decent gas mileage. It should work fine with your stock P'glide convertor. You can keep your stock rockers and pushrods if they are good and use their recommended springs.
Lift is .489 and duration is 212 degrees at .050 if I remember correctly.
Stovebolt's cast headers will be another good improvement.
