yep you prob have 3.73s....what RPMs you pullin at 70MPH?

 

 

 

I took a look at it while going down the interstate today and was getting a little under 2000 rpm at 70 mph. Somewhere around 1800-2000. This is with 285's not the stock 265's.

3.73s for sure.....due to the larger tire your final ratio is around 3.55 or so.

I see, I see. Is this suffice for my 285's or do i need to upgrade? It still gets up and goes off the start pretty good. Thanks for your help.

      Looking at ordering a '26 WT because I want a std cab, std bed

      No, not yet. Hoping I'll have something a little more definitive in the next day or 2. They seemed to be very confident they can order it. I do have some understanding of the whole allocations and restraints stuff so we'll see.   I think this is what I'm looking for.   3000 ORDER ACCEPTED BY PRODUCTION CONTROL

      Then you haven't read your book. It also says check every 400 miles.   If you need to add multiple quarts in that distance then reading the stick isn't the issue. Put the two together and it will make sense. Read it all.

      Weird drivability problem

      By CNH-320 · Posted

      Following up on my topic, I put an O2 sensor in it which seems to have got rid of all the b2s1 codes (I ended up having multiple codes). Next I’ll try to figure out the P0011 but I might focus on exhaust manifolds first, they’re getting pretty rusty. I’m hoping this thread will help someone in the future.

      My expectations are a bit higher.    No faded paint or dry rotted plastic/rubber. I use a dressing and a ceramic sealant. No hazy headlights.  No door dings. Small dent in the front bumper. All rock chips repaired. No brush scratches. No windshield chips. No fender benders. Limit damage due to a proactive plan the included ceramics and PPF and prompt attention to any exterior issue. NO RUST. Stays out of the salt and had the rear wheel wells Line-X coated as well as the bed which has a bed rubber and has been under cover since before I bought it. Washed and detailed regularly. Rex chewed up the tow button, got whacked and the button replaced the same week. He's leaned his lesson. If I can train a dog the kids are easier.    All suspension is original save the King Shocks I installed very early on. 50 years ago dad told me a good shock will keep the screws in the dash tight and the front end mint. He was right. Everything within new spec yet, tight and aligned well several times. Coolant system is OEM save the modifications I made early on. Not a single leak anywhere on this machine. (Did repair an intake leak on #4 during the HPFP replacement.) The injectors I replaced didn't need to be. They checked out great. One of those, while I'm in there with the manifold off and the fuel rail apart things.  Not a stain or abrasion one to the upholstery. Have kept is covered since new. Never had a carpet, it's a work truck but the carpet squared I laid on the floor have keep the factory rubber liner MINT. Ceramic wind tint helps preserve the interior.    Original BRAKES with 60%+ left of the pads and rotors mic excellent. We just did a full preventative brake service. Disassembly, clean inspect including measurements, lube, Dot 4 power flush including ABS system.    OEM battery. OEM vacuum pump. In fact the only things not OEM are a pinion seal the high side pump and injectors and a small plastic shield around the starter. All hoses/belts etc.. are still in service and doing well. Original tires lasted 125K and had I known some additional details would have made it to 150K with legal tread. (Date out is six years, not 5 and Continental says they are good for 10 so I pulled the trigger to early)   I never let my children or grandchildren run the show. Feet on the floor and hands in your lap. Dog gets a pass.    A truck is a machine the gives you back whatever your willing to put into it. Same as a computer or a butter knife. I use a shovel but I scrap it, hose it off and oil it when I'm done with it. My original spade I've had 60 years.      Set the bar higher...you spend less money. No, before you ask, I have spent a fraction of the cost of a new truck in my entire maintenance program including disposables, filters/fluids etc.
