    10W-40 for Chevy 350

    All good @Grit dog. You think our specialty oils are ridiculous in small town northern bc? You should see what they ask for a bottle of water in the stores while all our rivers are all fed from short runs from glaciers. Mercury recommends 25/40 in all their engines (including the 350...

    10W-40 for Chevy 350

    I only posted because the OP was questioning concerns of cold start differences between 10/30 and 10/40. There is none. Didn't see where anyone else answered that. I have never looked at the Castrol. I was referencing the mercury oil making a point that these engines don't mind heavier grades of...

    10W-40 for Chevy 350

    10/30 and 10/40 both have the same cold start viscosity rating. I would not be concerned with increasing the viscosity slightly. Watch your oil pressure. Too high, adds additional strain to the cam gear and pump drive. Look at a marine 350. Internals are the exact same as what's in an auto with...

    Comments on gear pattern?

    Kind of looks like your pattern is walking in the first photo. Did you check the run out of the ring gear?

    Are front wheel bearings adjustable?

    Yes even timken. I would bet a few bucks that if you grab some timken wheel bearings for your truck from the local parts store and open them up, they will be stamped China. That's not to say they are garbage. They are built to timken's strict specifications. IMO though, i would (trust) be more...

    Are front wheel bearings adjustable?

    You have to disassemble, clean and repack the bearings. It is required at regular service intervals. If the bearings do not have defects that you can feel with your fingernail and are not discolored from heat, then repack and reuse them. Assuming the bearings are original, I would trust them...

    Best value coolant pressure tester

    I use the Stant kit. Been packing it around in my service truck for at least 25 years. Probably gets used 20-30 times a year. Even the case has stood up. They are a solid kit.

    Rattle can noise when accelerating from stop

    Do you have hub caps? Maybe a rock found it's way in or possibly a wheel nut fell off?

    6.7 Cummins Suburban Build

    EFI live is/was very popular in these parts. Not sure if they are still around though due to the epa crackdowns. What most did was just the turbo/back exhaust. The tune looked after the rest.

    Removing a leaf from a spring pack...which one?

    I think the slip should be away from the shower head to keep the water out when things get exciting in there....

    Loctite, which one and where?

    As a rule, loctite is not a good idea with aluminum. Using it with fine thread is also a waste of money. Every screw that has gone back into the chassis I am working on gets never-seize, but we deal with a lot of crap on our winter roads. Correct torque is more important for fasteners as...

    Cool project. Not sure if I missed it? Did you have a plan for the charge air cooler?

    What should I sell engine & tranny for?

    It is crazy what some people will pay for things. I would suggest posting an add on your local buy and sell or CL or whatever. Ask the $1200 while it can be heard running and driven. Never know, it may pay for the whole swap for you.

    What have I gotten myself into

    Welcome! Any pics of inside the box? Curious if there is any anchor points for a boom or something? In the 80's I dabbled with a friend for several years in the salvage business. He had a '69 c30 with a pto driven 10k (or possibly even a 10T) winch mounted at the front of a steel flat deck with...

    Duramax/Square body swap? Thoughts?

    Pretty interested in seeing what you decide to do with yours. I could see myself doing a similar move down the road. Would be a bit different for me though. I have an '08 2500 4x4 with lightly used LMM but the body is rotting out on it with it's frame not far behind. Have been putting some...

    Peanut Port #14092360

    It is a bit tough to tell from the angle of your photo, but it appears there is a big variation in the amount of threads exposed on the rocker studs. As a rule, that is not the case on a fresh or low mileage head. It is the first thing I look at when removing a cover. Part of diagnosing...

    Frame welded, dangerous?

    That is not the correct way to weld a frame. It would not pass a safety inspection in this part of the world. With consideration of frame deterioration in the rest of the photo, I would be looking for another frame if serious about your restoration.

    Electric fuel pump question

    First thing I would check, is to see if there is a negative pressure building in the fuel tank. Open the filler cap to the tank when it happens and listen for a hissing sound. Could be a restricted tank vent. Next, I would be questioning the fuel pump itself or a plugged suction screen in the tank.

    1982 C30 HOLMES WRECKER - $3,500 (PLANO TX)

    Back in the 80's, I had to have a couple of my squares rescued off-grid and hauled to town behind a single axle K30 with just a simple A frame on the back. Lol. Times have changed!

    K20 pulling 19k lbs...

    According to the link posted above, (https://www.gmsquarebody.com/threads/1985-gm-towing-guide-and-1981-dealer-towing-video.16699/) replacing the diesel in my '86 K30 with a 5.7 is going to increase my tow capacity. :cool: Thanks @Blue Ox!

    Oil pressure

    Installing a pick up tube is not considered to be throwing parts at it. Pulling oil from the top of the sump instead of the bottom, will more than likely be introducing aerated oil to the galleries. A new pump and pick up can be bought for under $100 if you are on a tight budget.
