    Not trying to stir the pot, but minus old mechanical engines with actual rack adjustments "running overhead" has more to do with valve and valve train life vs performance. Tight valve settings can cause burnt or dropped valves, loose settings "hammer" the valve train and can cause roller skidding. When I was in college, we had a Series 60 and 3406E on engine dyno's. Instructor had us set overhead all over the place and ran engines to see if any difference in torque and HP. It was no difference. On Cummins Celect engines, I will no set injectors unless asked to because usually ending replacing an injector because deposits that get broken up by the adjustment procedure.
    I am a firm believer in running overheads and usually do it more than manufacturers suggested hours or miles.

    if someone would be willing to teach, id do it myself. I love tickering & learing new things. I did uti then got a job at bmw but pay was terrible at only 15$ hr. I regret not doing the diesal course and getting a job in that then becoming a trucker. I can always go back but got too many bills now.

    Thanks to you guys i will be doing it around 100k for now on, but still really want to learn how to do it myself. Am still learning about diesal trucks. Minus paint n interior my truck mechanically in almost new condition for a 96 and i get 8+ mpg around 70mph. If the wind is nice i get around 10. I love this truck n it will prob die with me. I love dyno stuff. Would like to take my truck to Pittsburgh power in PA someday.

    If you are getting that MPG at that speed... Don't touch anything unless you have to. Get whoever has been running the overhead to run it and don't change anything unless it breaks.
     
    JoeyJunk and Turbrospeed Thank this.

    Well i want to make it better cause i only go 67-70 due to having a 2.9 rear diff ratio and am at 1250-1280rpms in 13th gear, So i wanted put a 3.36 ratio, remove the power divider, move the rear diff to the front and put a dead axle. I want to go 65mph at like 1300-1350rpms.

    Am already heading to miami tomm and just going to get the overhead done, so i dont have to come to Miami atleast until next year or never again. I have a guys number from Charlotte that supposetly does the overhead for 350$ according to the driver i met in Laredo. I would like to find some near Austin or San Antonio that does it since i like an hr from there.

    About all I do now is Overheads and maybe A/C jobs. The last Saturday I worked I did two overheads and a service and replaced battery cables and my back was hurting so bad I thought I was going to die. LOL I only work on Saturdays also.

    I hear ya...my back has been not 100 percent either since last year i had a accident in my car with a dam deer and then i decided to do massive hand sanding/paint. I have gone to the chiro and gotten lots of massages at places, still not like i use to be. I just moved also so that didnt help either. Cant wait to go home and rest in which i doubt ill do cause when i get home from the road i just want to do a million things. Also the truck needs a oil change.
