4.0L HO Jeep Engine Build

Hey, I was a little curious to see how the build has continued to work. I know you mentioned you would go with the Lunati cam if you had done things differently. Besides adding the possible 10hp (+/-), what effects would it have in terms of mileage, TQ, etc? I haven't had a lot of experience with cams, so input would be much appreciated. Also, I can't remember if you were using the old injectors or the 4-hole mustang ones? I've heard of people running into starting issues with the 4-hole design is why I ask. Thanks
