    Engine advice—How screwed am I (pics)

    You can buy a reman long block for as little as 2K with a warranty. (just looked it up at Autozone) You could pay a shop to install and still be under 5K including a new radiator and water pump.

    AC issue replaced everything

    My 1990 had the orifice tube in the line on the right fender well. My new Condenser had the orifice in it. If you have both it's not going to work.

    power steering pump whine issues

    When I worked at GM dealers in the late 70's and 80's we used to add a little EOS to the steering pump and it would quiet them right down. GM EOS is about the same thing as STP ( Engine Oil Supplement)

    Aluminum Heads to 90 C1500

    I would recommend you take a long look at https://blueprintengines.com/ They build engines and dyno everything. I plan to buy one from them when the time comes but even if you plan to self build look at the parts they use and the results they achieve. This research should get you going in a...

    1990 c1500 Engine Upgrade Questions?

    I have the same goal in mind but would like to keep the TBI and stock Ignition system. Just my uneducated opinion, but that cam seems pretty aggressive at 2500-6000RPM. Personally I would be looking at an "RV/Towing" Cam but you do you! I like you header choice. I also have a 1990 C1500 and...

    Idler pulley/tensioner question 1990 5.7 with AC

    1990 C1500 with 5.7 v8 and AC. I need to replace the idler pulley on the tensioner which should be a no brainer but having a part ID issue. Parts lookup calls for a GM 10129560 which crosses to Dorman 419-610. OK but those are smooth pulleys with no flange. The one on the truck has side guides...

    90-1500

    Just read from Page 1. Nice work. These upper control arm bolts without cams look factory. They put plugs in there at assembly so no cams needed. That means the truck has never had a real FE alignment but just "Tow and Go" There is a $29 tool to remove the plugs before cam bolt install. I highly...

    Complete Exhaust System From the Head to the Bed 1990 C1500 Single cab Short bed

    I do have a small MIG that is perfect for exhaust work and other light stuff and that sounds like a pretty good option. I wonder how Summits Return policy is????? If I did this I would just buy a big pile of everything I think I might need and then return what I dont use. This is the method I...

    Complete Exhaust System From the Head to the Bed 1990 C1500 Single cab Short bed

    My Mistake on the description. 1990 C1500 Short Bed Single Cab 350 with 700R4. I have not been able to find what I am looking for and I am normally pretty good at looking for stuff. I know I can do the headers and then just send it to exhaust shop but if a full kit exists I dont want to miss it...

    Complete Exhaust System From the Head to the Bed 1990 C1500 Single cab Short bed

    Seeing a whole bunch of Header threads so I thought I would post one too. I am looking for a Complete Exhaust system. Short, Mid, or Long that comes with the pipes and mufflers. Side Exit, Single or true dual. DOnt care but I want to buy it all together in one shot that will fit. I dont need...

    spraying rear diff oil after new driveshaft

    Did you use a Dorman 697-500 kit? If you did, as I mentioned in an earlier post. The seal for the Dorman Yoke is National 710506. I had a conversation with a Dorman Engineer a while back. The Dorman Kit 497-500 is designed to minic the superseded design GM Yoke and seal. Apparently GM had an...

    spraying rear diff oil after new driveshaft

    I went from 342 to 373 . I think you really have three options at this point. Take it to a mechanic. Pull the rear end and take it to a mechanic. Get a junk yard rear end. #3 will be the cheapest but 1 or 2 will get you brand new stuff and likely a warranty.
