    Center/carrier bearing orientation - 76 C20 suburban

    Heard a clinking noise while running around testing the new build/motor. I think the culprit is the dust guard moving around that I put on the new carrier bearing I installed. Not sure If I was supposed to include that but any ideas on how its supposed to be installed? I could maybe epoxy it...

    mark 4 454 engine oil cooler lines

    I have a auxillary oil cooler on the 76 454 and need to replace the lines that go from the oil filter adapter to the cooler. After a pretty good search it seems that no one makes a repop so I guess I have to make my own. Any suggestions on fittings / hose type to use? Should I get AN fittings...

    454 Crankshaft rod journal

    Starting to mike the crankshaft bore and journals to check for runout/oil clearance when I noticed this blemish on one of the rod journals. Have no Idea if the engine ran with this or if it happened at the machine shop or during transport/storage. It looks more like some kind of breakdown or...

    1976 C20 Burb: 3/4 ton fuel system and EVAP

    Starting to plan the fuel system and am trying to find out if my truck ever came with the EVAP canister/system. I have read one thread on another forum that states up to 1983 3/4 ton vehicles were considered heavy duty and did not come with the charcoal canister. Those vehicles reportedly came...

    Mystery washers

    Assembling my steering and suspension back together and noticed these two washers which I mistakenly did not label. Not sure if they are a big deal at all but my OCD will not let it go. I have checked through all the photos I took during disassembly and cannot find out where they came from. I...

    Header back exhaust fitment for C20 454

    Further planning out the build while the block is at the machine shop. I want to go with long tube headers, maybe a set off of summit, so I will need to replace the exhaust as well. Does anyone know of a good header back system for the 1976 c20 big block burb? The flowmaster #17742 says it fits...

    76 C20 454 harness mess

    Just got the truck home and started to dig into the hectic wiring situation. My electrical knowledge is admittedly pretty weak so I am learning as I go. So a little background on the truck. At some point there was a second battery installed (unless some models came with two) along with...

    Fuel system conversion advise

    Just bought my first square body. Its a 1976 C20 burb 454. Its a beautiful truck with extremely little body and frame rust. The previous owner did a tbi conversion. Long story short the truck does not like to idle, wants to bog down when given above 50% throttle, and seems to be running...
