Inframe

She's got 1124xxx and counting, had rods and mains done once, so it's due. Runs really good with very little oil used between changes, is leaking some around the compressor. I do a lot of work on the truck myself but I'm just not up to inframing. But I know I want it done right so there was no question about it going to GA. Plus I'm really looking forward to meeting Mr Haggi and Rawze.
So I also want to replace the cams and injectors because of the miles. But I was wondering with changing cams and injectors can it be built to different specifications. I'm by no means wanting to jack up the HP and torque. But can you build a better mouse trap for say.
I have a 2008 Prostar with 871, SN79275004, with a Ultrashift and if I remember correctly 3:55s. I pull a flatbed and I'm heavy a lot but also dead head a lot. I don't run the truck hard and keep my RPMs up and boost down. I also never let it get hot. I'm always manually turning the fan on around 195. It’s just a habit and I feel it's helped it last so long. When ever I stop and the truck is idling I turn the fan on and leave it run.
Also leaning toward changing the oil cooler also, thoughts on that??? This truck is a keeper for me so I want to do it right. But if I can make it better then I'm open to changes.

So just doing a update on the inframe. So I got to Mr Haggai's in Griffin GA Monday morning. Got the car off the dolly and the dolly off the truck. Went to pull the truck into the shop and the air pressure was down to 80. I was able to get it backed up to the door. But we had to put some boards under the front tires to get it in the door because the truck is really low. They then used a hose to air the truck up and got it into the shop. Allison, Jerry's daughter and engine builder, checked it out and found that the compressor had went out. Talk about timing. But since then she has it torn down and has done an amazing job. So I will give a brief overview of how things look as far as wear once she got it apart. Cams and rollers worn but no flaking but some scratches. The Jake assemblies were really worn out. Injectors tested good, and not a lot of carbon in the head or on the pistons. Some of the cam bearing are scared as well as the mains and rods. When she pulled the pistons one of the rings was broken. The liners are smooth with no hash marks. She also said that the liners were not to specs but most likely because of all the miles on the engine. There's a huge line of parts ready for install. Here are some pictures of some of the removed parts.
