    LE9 305 w ESC Performance upgrades '86 k5 Blazer

    Hi all, I just picked up a new to me 1986 K5 blazer. Glovebox build sheet says it has the LE9 5.0 Liter V8 Gas GM. It supposedly has 190k on it and runs really well except for some blue smoke unitl it warms up. I have the 700R4 4 speed auto and thankfully GT4 rear axle 3.73 and NP 208 transfer...

    Gauge Cluster Swap

    I replaced the oil pressure switch with the big bell shaped sensor SP174 and the temp sensor with a TS76 temp sensor. I’ll have to get the voltmeter next and ring out the wires from the sensors to the cluster to see if they are in the correct spot. I had no idea the idiot light oil pressure...

    Gauge Cluster Swap

    I’m trying to swap my idiot lights to gauges in my 86 k5 Blazer. I tried moving the pins around The big connector but I can only get the volt gauge to work. I used a pin out on another post but some of my wire colors don’t match. Fuel, temp and oil are all pegged and gauge lights won’t...

    K5 Blazer values… possibly buying 86 k5

    Squarebody day! Did some troubleshooting and the front driveshaft turns if you turn front wheels when front end is off the ground. Removed a hub and don’t see anything broken but guess I’ll order hubs and hope that fixes it. Also tried to adjust TV cable for 700R4 but it’s not self adjusting...

    K5 Blazer values… possibly buying 86 k5

    Thanks! Runs good! I guess it has a 2bbl quadrajet. May need to lean it out since I’m at 7k ft altitude. Small things to fix, hood rubs the cowl when opening, ac was converted to r134, compressor spins but not very cold. Needs new front driveshaft, dash or cover, will prob swap to a spare...

    K5 Blazer values… possibly buying 86 k5

    Bought it for 5k! Drove home 80 miles on interstate. Did great except vibration from front. Hubs are unlocked and it’s in 2WD but front driveshaft still turns and has slop in it so that’s the vibration. Front Drive shaft should not be turning in 2WD correct? Of course wheels aren’t engaged...

    No reply on the cheap no pics one on Craig’s. The 86 is only 1.5 hr from me so not bad

    Eh think I’m going to pass… Damnit, I better still go test drive it, going to ask if he will go any lower.

    I got some better pics. The low res Craigslist pics were hiding some wrinkles in the drives door. Hmmm wonder if he’d take 5k…. The build sheet says tan top and it looks like it may have been repainted white which is fading but overall paint is decent for being original

    K5 Blazer values… possibly buying 86 k5

    Seems like the market is finally cooling off? I wish it was a higher trim and had the 350 but I have the old 400 out of my k10 I could freshen up and drop in. Of course it always looks better in photos than it actually is but I’m going to see if I can test drive it tomorrow afternoon. So...

    K5 Blazer values… possibly buying 86 k5

    I watched an old Truck U episode on YouTube and they were all about huge lift and cowl hood. Not for me. I’d prob put 33” tires on this and leave the 4” lift unless it rides like crap. I put tuff country springs on my k10 and it rides pretty good for a short wheelbase squarebody. From the...

    I own a 79 k10 and if I go checkout the blazer, will check the frame for cracking at steering box and rear upper shock mounts. Any other things to check besides a test drive of course and rear window operation.

    K5 Blazer values… possibly buying 86 k5

    Considering buying this. Guy will take $6k. Have yet to go see it as it’s an hour or more away. What’s a fair price? Seems pretty rust free but lots of miles and stripper model. 1986 chevy k5 blazer carbureted 305 700r4 transmission (3 speed with overdrive) tires fairly new 80% recent...

    Tank replacement for EFI

    @SquareRoot Are you connecting the fuel injection supply and return rubber hose to any of the original metal fuel lines or running rubber hose from the tank all the way to the engine?

    Tank replacement for EFI

    Thanks for the pics. I'll have to lookup the weatherpak female connector or just hard wire it. Do you use all rubber line rated for fuel injection or off brand like evil energy? Gates 42195653 3/8 for feed...

    Tank replacement for EFI

    @SquareRoot I really appreciate your help! I updated my previous post and will probably go with: Delphi FE0114 pump Dorman 692044 sender? - Seems like this is the only sendor for a fuel pump. Or order a TBI pump housing assembly and swap out the pump?

    Tank replacement for EFI

    I think I’ll order a 87 tank for the driver side and use the vortec truck in tank fuel pump if it will support my 500 hp motor. Or will use this pump sometime mentioned here https://www.summitracing.com/parts/aei-11569 I’ll just bypass the valve and wire and plumb the driver side tank as a...

    Tank replacement for EFI

    Hmm, I seriously considered the pro flo 4 system but I just put a rpm intake on my new motor and got the sniper 2 complete kit for $1500 out the door. I guess I could resell the Holley pump if I don’t use it. The sniper 2 kit I got came with a Holley external regulator...

    Tank replacement for EFI

    just purchased sniper 2 kit which comes with external pump, regulator and hose. My 79 K10 has the dual 16 gallon side tanks. I just installed a 500hp blueprint 400 crate engine. I’m guessing I can’t use the 96-99 vortec in-tank fuel pumps? If I go with the external Holley pump, can I just run...
