    NP205 Pops out of low

    I had a similar issue on a 203 and it was also the linkage. Soaked it in PB Blaster until I could free it up and then worked it back and forth everyday for a few weeks. The truck had been sitting outside for years.

    Help me understand 5.0 disparities

    The size of an engine has little to do with performance, or we would all be running 460 Fords. They can be the same size but share nothing else, ie cam lift, valve size, head breathing capabilities, carburation, as well as the quality of internal design.

    How much more power can a 5.3L make without hurting road manners or gas mileage?

    Just swapping out the typical 5.3 for the old 350, without any modifications, is going to make a pretty noticeable difference. This is coming from an old school, gen 1 sbc diehard fan who also happens to be able to critically think. Reading about what it is you are wanting, and some of your...

    Engine dieseling diagnosis…

    Seafoam works, but if the issue isn't carboned valves or a gummy quadrajet, then you might think it is useless. Personally, when I get a motor that has been sitting, or driven in a poor and unmaintained condition for an extended period, I start with a full can of Berrymen B12 in the gas tank...

    Heater core requirement for new engine install break-in/ test?

    No issues. Just get a flush tee and a couple hose clamps, tie the two heater hoses into the tee and you are done.

    I need help and to know what this truck is worth

    $500-1k for the truck in the photos with no title and the same guy has owned it for decades makes that a good deal as a parts truck. The bed, fenders, doors, drive train etc can all be used on another project and spare items sold off to offset the costs. As a donor truck, the money isn't as...

    I need help and to know what this truck is worth

    Squarebody C10s aren't so rare that you have to cut a tree out of the frame to own one. 1K is top dollar on a good day but I certainly would start with that as an offer. I'd also want to know who is responsible for cutting the tree out? If I was, my time and chainsaw chain would be coming off...

    Need some advice please

    I'd pay the $400 and take to your bud's place and sell it for $400 just to say it did it on my terms. It would be hard to lose something like that and forget about it.

    Door panel recommendation

    When I need a lot of parts I buy a parts truck. When it is something like door panels, I get on FB Marketplace and do a search. If the stuff isn't what I am looking for, I keep searching farther out and every day I come back until I find what I am looking for. So far that method has worked for...

    Initial $2k investment to ‘85 c10

    Well, the driveline sounds like it is done. Brakes and suspension. Electrical. Keep the rest in the glove box for use as needed.

    USA1 Industries

    My experience with LMC is just good enough that I will still do business, but buyer beware. I order a chrome tailgate cap for a 1970 C10. For those who know, the cap runs the width of the tail gate and is square cut on the ends. I received a cap that was about 2/3rds as wide and with curved...

    USA1 Industries

    If I am restoring a squarebody to keep, it is doubtful I'm going to wait more than a month or two for door panels. If I am restoring a squarebody for resale, I would not use USA1 at all. I get that they may be nice folks, but good customer service will go along way to preventing threads such as...

    SOLVED! 1987 350 TBI Timing advance issues

    I put an ignition module in a 74 c10 about 6 months ago. I bought it off ebay, so yes, it came over on a steamer from the far east. It lasted about 2 months. Ok, so an American made IM was about $70 locally. I figured, what the heck, I can get a whole distributor with a coil, cap and module for...

    Careful buying online- Camaro 1979

    I have said it before. 40+ year old cars = a lot of owners, mods, repairs, fabrications (mostly partials) and sitting. Unless you have first hand knowledge of the vehicle's history, expect the above and you won't be so disappointed. Most sellers, and to be fair, some are well meaning, take a...

    Left hand dipstick

    I believe the driver side dipstick location was on motors up thru 1979.

    How should i build my engine, 1979 chevy k10

    It sounds like your engine is a 350. You should probably check the numbers on the block to find the year and specifics. It would have originated in something from 1968 and later. Also, if it has already been bored .30 or .60, you may need a machine shop to confirm the block is still usable...

    79 c10 engine upgrade help.

    Welcome and congrats. I love the Big 10s. If your truck has been sitting for any length of time (you mentioned 1994), change the fluids, filters, and look for wear with hoses and belts. Before spending any money on upgrades, pull the plugs and check how they are burning. I'd even run a...

    1984 C10 305 stall at low speeds, loss of power during accel

    I had a guys GMC squarebody in my pole barn about a month ago. K15 350 quadrajet. It would not idle at all. Smoked so bad it looked like a wet leaf fire. Backfired thru the carb, hitting on about 5-6 cylinders. He said he was tooling down the road and it just started acting up. He had oil...

    1984 C10 305 stall at low speeds, loss of power during accel

    I think you should do the easy stuff first. Yes, it could be a vacuum leak, or something else, but gas that is over a year old is low hanging fruit. Old gas gums up components in a carburetor, sticks the float, plugs filters, clogs pumps. I'm just saying start your process from the beginning...

    1984 C10 305 stall at low speeds, loss of power during accel

    Many times, actually most of the time, we outthink ourselves and try to skip to level 5 when it is almost always the simple stuff. I would at a minimum drain the tank and top it off with leaded fuel. I'd throw a can of Berry Man B12 in the tank for good measure, and run it. After the next fill...

    1984 C10 305 stall at low speeds, loss of power during accel

    I read thru your initial post but not completely thru the second one, however I just have a simple question. You said the truck sat for over a year between blowing belts and hoses and the repairs. You listed one possibility for the current driveability problem as bad gas. Have you drained the...

    1973 K5 Blazer full removable top a little high but is it rare???

    The Craigs List Blazer for sale in the OP is all just speculation and fun for discussion. IMO, no one is buying that truck for work, hauling or any purpose other than fun. So what is a fun old SUV worth? From the pics, the bumpers and body look straight, 5 matching wheels with good tread on the...

    Got an '82 C20... its killing me with electronics issues

    Follow your power beginning at the battery and if need be, ending at the switch. On the firewall between the distributor and the power brake booster is a small junction block. It should have two separate posts. There should be a wire coming up from the starter solenoid to that post. It...
