    1988 v30 454 dump body lift advice

    Don't lift the truck. I would never use blocks on a work truck. Buy 255/85-16's next time you "retire" the truck. They do not require spacers. Been running them for years.

    1988 v 30 454

    Not entirely correct. In 1988 you could still buy a 2 door square body pickup with two provisions. It had to be a 4x4 and R05 dual rear wheels. My 1988 V30 regular cab pickup built May 1988 in the Janesville plant. Always asked for 1987 K30 when at parts store. Page from 1988 showroom brochure.

    No one has a practical use for dually split rims anymore, right?

    If you were about 1000 miles closer I would take them off your hands if they are the "split ring" model. It's the solid ring 2 piece that is most dangerous and I would not use them.

    Different tires or LSD in front or back?

    I like 255/85 16's on my 3/4, 1 ton plow trucks. BFG Mud Terrains. Narrow gets more lbs per sq. in. for traction on ice covered snow traction surfaces. No lift or body modifications required.

    6.5 Turbo reliability for an RV?

    I like the 6.5 T in my 94 K2500 Suburban very much. Has the extra engine/transmission oil coolers and a huge radiator. Never over heated with any load I pulled. 4L80E and 3.73 gears with 265/75-16's BFG Rugged terrain TA's. With camping gear and pulling the little rv trailer I have driven the...

    HELP me decide. '91 S10

    NO, we were having a family Get together/BBQ. i asked everybody to line up so that I could get that pic. The LT 215/75-15 tire did a great job on my 2000 S-10. Most of the BFG truck tire line had 3 ply sidewalls.

    HELP me decide. '91 S10

    Well, on my 2WD S-10 I ran LT 215/75's as it was the smallest BFG I could buy in a light truck tire. I got along fine with the stock wheels. Some Outlaw wheels look nice You should know that you will get ABS faults running different size tires front and rear. Have more experience with the 4WD...

    1979 Crew Cab Dually 496 - Tire Wizard Needed

    Well, hard to tell from your pics but, I'm wondering who made those wheels. I have been driving GM duallys since they started building them and never had any problems running 235/85 or 255/85's on any of them. Hauled plenty of heavy loads without sidewall rubbing and tire troubles. Loaded with...

    K30 454 headers

    What works in a 2WD often has fitment problems on a 4WD. When I replaced a 6.2 with a BB in my D30 I had a couple options open to me. There were some welded stainless steel headers on a donor motor from a Blue Bird bus and a near new stock set of headers I bought at a local salvage yard. They...

    Small block... buick? Oldsmobile? PONTIAC?

    Get a 472 from a 1971 Eldorado and that truck will run! Most owned by people that took care of those Cadillac autos. There was a company that made mounts for them and other necessary items. They even had custom flywheels so that you could mount manual transmissions to them.

    35s on stock Chevy wheels

    While I do not run covers I have always run the 235/85-16's on my K30 single and dually 4x4's on stock wheels and Alcoa's. Never any clearance issues.

    can you D30 to K20 front leaf swap??

    I have always believed there was a slight steering symmetry to this observation. Around here going back to the mid 70's it was usually told as,"they all do that". I had new GM's as well as used ones encounter the same affliction with boards attached. Seen guys loosen cab mounts and try to"square...

    can you D30 to K20 front leaf swap??

    I am curious why you are having clearance issues. I have run 235/85-16's for years without any problems and 33/12.50-15's on the half ton with an 8.5 Western Pro Plow also. What is the wheel width and spacing of the hub? Likely the rub is with the running board on the passenger side, correct? K...

    Options for beds - aftermarket, used, new, substitutions

    I think a M105 bed would be a nice fit.

    Fleetside tool box...

    Last under bed storage compartment I had was on my 1972 GMC 3500. It was located on the passenger side. It had the 8.5' bed. There was the 22 gal in cab tank, the factory under bed 18 gal driver side auxiliary tank, and I had a custom 30 gal tank filling up across the first 6" inside the bed...

    Np203 leaking

    I have run a few part timed 203's well over 100k without issues of oiling. I always added a bit more oil to the transfer case as instructed by one of the kit manufacturers back in the day. It seems to have worked well. Also when looking for a better 203 for replacement for the earlier years part...

    Going to look at a military K5...

    I loved mine. My son has the M1009 now and he did replace the T400 with a diesel version 700R4. The 3.08 rears work good with the stock 31/10.50 tires.

    What is a NOS grill worth?

    I actually have a couple more of these signs. One for the rear of my loads and at least one other if my escort vehicle needs to borrow one.
