    mark 4 454 engine oil cooler lines

    Thanks for the advice fellas. nvrenuf, ill probably keep this vehicle forever so I might as well. Ricko, I like that idea of using the power steering hose with the an fittings. thinking 1/2 inch or -8 AN sounds close to the original size hose/fitting. Just read this article...

    mark 4 454 engine oil cooler lines

    Thanks man I will check that out. What do y’all think of making a AN fitting to adapt to it? seems pretty simple just looking into it.

    mark 4 454 engine oil cooler lines

    I’m pretty sure they were the hydraulic style but I will check. There’s a chance the fitting could be long gone. Do y’all know the approximate length of the lines if I just get some new ones made?

    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...

    Rocker tip alignment big block

    Searched this and some other forums and get multiple answers. mostly the exhaust roller rocker tips do not seem centered on the valves. First big block build. It will be a 461". Pretty sure I got geometry correct with the smallest tip pattern on valve when measuring pushrod length. These are...

    Sorry for the typo yes I did mean it is probably somewhere around 0.005.

    454 Crankshaft rod journal

    Its hard to quantify the actual depth of the defects. My guess is maybe 0.05 inch. No more than 0.01 inch. Think this is still acceptable? What depth would be in good faith to run?

    454 Crankshaft rod journal

    Yes, there is depth to the defects. You can tell the darker areas are lower than the polished part of the journal when you run your finger over it. There are just no sharp edges.

    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

    Interesting that some 3/4 ton came with it and some did not. I think in this case I will try running a short fuel hose from the third metal line on the sending unit ending it somewhere near the filler neck or rear of the vehicle. Will top it with a rollover vent valve such as...

    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

    I think you are right. I also checked the transmission mount washers for the th400. Same OD and thickness but the ID is much smaller.

    I appreciate the insight but the rear shocks are still on the truck

    Mystery washers

    Better question is have yall ever used washers under control arm bolts?
  17. T

    Mystery washers

    They are a larger diameter and thickness than my shocks' washers. I am thinking lower ball joint as well because the wear marks kinda line up. It is hard to tell with the photos taken before disassembly since everything is covered in dirt and grease. Also it seems like others do not have washers...

    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

    Looks like pretty nice work. Clean truck as well.

    Header back exhaust fitment for C20 454

    hmm that seems like a reasonable option also. I would have thought a shop would charge a arm and leg for a custom exhaust but maybe ill call to price it out. Would be cool to do one yourself though. I would like to find a way to keep the system able to be broken down. This vehicle will...

    Header back exhaust fitment for C20 454

    Looks very clean I like it. Is that kit a weld together or slip fit?

    Is there a particular universal kit you have in mind?

    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...

    6 Speed Swap

    Thanks for the info guys. I will give level 7 a call soon and see what they can do for me. Contemplating btw a 4 speed sm465 or the new heavy duty 5 speed tremec that is supposed to be comparable to the nv4500. Cost does play a factor in my decision. Will probably create a new thread soon to...
