    ‘83 K5 350/4wd: aftermarket oil psi switch/sender/choke heater wiring question w/pics and schematic

    Okay, along with my other post, I think I understand what you and @EvilGenius are saying. I must have misinterpreted the colored ClassicCarWiring.com diagram that says “Oil PSI SW (6 cyl w/o gauges-see pic) as meaning it was only specific to 6 cylinders (thus this separate post asking what to do...

    ‘83 K5 350/4wd: aftermarket oil psi switch/sender/choke heater wiring question w/pics and schematic

    Okay, I understand your explanation and is the way I understood it in my head, thanks. The Haynes manual (see photo) shows the DK Blue wire (from switch) connected to the LT Blue wire (from choke) at the switch and from the switch, the DK Blue wire connected to the Tan wire that goes to the...

    ‘83 K5 Wiring diagram V8 vs V6 Firewall Block blue wire for oil psi switch requirement??? See pics

    I also posted another question/scenario that may comply with your response. This post is specific to the blue (schematic dashed) 931 wire that goes to a “Oil Psi switch (6 cyl w/o gauges)” as shown in the pic of the schematic. I may have already satisfied this requirement as explained in my...

    ‘83 K5 350/4wd: aftermarket oil psi switch/sender/choke heater wiring question w/pics and schematic

    ‘83 K5/350/4wd question: Please confirm my wiring/splicing is correct per the Haynes manual schematic. Tan wire from dash oil/choke indicator through firewall to new factory style oil psi sender (at distributor) spliced into dark blue wire to the oil psi switch and spliced with Lt blue wire to...

    ‘83 K5 Wiring diagram V8 vs V6 Firewall Block blue wire for oil psi switch requirement??? See pics

    ‘83 K5/crate 350/4wd: I am redoing some damaged wiring. The electrical schematic I have shows a blue (dashed) wire from the firewall block to an oil psi switch (6 cyl w/o gauges). I’m not entirely sure if this wire was connected to anything before I pulled the factory 305 to install my new crate...

    ‘83 K5 Gas Tank and Skid Plate Best Protective Coatings???

    Hi guys and girls! I just finished restoring and priming the gas tank and skid plate/rock guard. I would like to get some ideas on what type of coating or overlay to apply in an effort to better withstand flying rock damage and corrosion i.e. rubberized coatings, adhesive protectants, thick...

    83’ Blazer: In need of a factory muffler heat shield

    A catalytic converter is not required thus my reasoning to remove that heat shield. What do you mean by “up to 300 HP”? My engine is a 385HP SBC350. Is a single 2-1/2” or 3” exhaust not enough flow or do I really need dual exhaust to get enough flow?

    83’ Blazer: In need of a factory muffler heat shield

    Thank y’all for the input. I may very well try to find one in a junkyard since I’ve exhausted all other resources. However, I did find aftermarket heat shields that attach to the mufflers as another possible option. Let me ask you another question, since I am considering installing true straight...

    83’ Blazer: In need of a factory muffler heat shield

    Mine was a factory 305, but I installed a new GM crate 350. Just thought I would see if anybody had another heat shield so I could run dual exhaust. Thanks for the reply!

    83’ Blazer: In need of a factory muffler heat shield

    1983 Blazer: I am in need of a factory muffler heat shield for the right side for dual exhaust. I’m assuming that my Blazer originally didn’t come with dual exhaust and is the reason it didn’t have a heat shield for the right side. I’ve been looking online but can’t find one. I’ve checked AMD...

    Can you believe this???!!! TC/NP208 Adapter/700R4 trans crossmember mounting/question?

    I just wanted to provide a follow up to this post. I have called multiple reputable 4WD specialty companies around the country and was told that SLE’s are no longer manufactured for NP208 transfer cases. I was also informed that with a 4” lift that with the proper aftermarket ORD adapter mounts...

    Help with difficult problem!!! ‘83 K5/4” lift/NP208 mounting height with incorrect homemade spacers vs correct spacers???

    The 7/16” bolts did work. Not sure why the bolt holes were grinded open for 1/2” bolts to be installed. Thanks for all your input!

    Help with difficult problem!!! ‘83 K5/4” lift/NP208 mounting height with incorrect homemade spacers vs correct spacers???

    Okay, the engine and trans are not yet installed. I stumbled across this issue when trial fitting the crossmember and adapter with the new mounts. I cannot get the one bolt hole to line up and don’t think that even a 7/16” bolt would fit. Maybe a 3/8” bolt but is that sufficient? Or, should I...

    Help with difficult problem!!! ‘83 K5/4” lift/NP208 mounting height with incorrect homemade spacers vs correct spacers???

    Thanks, if I turn the crossmember around more bolt holes are off. When positioned when one hole is off, it is off about a 1/4”. The bolt is a 1/2” diameter. I also need to know how high or how low the adapter should be considering the 4” lift. Obviously, the angle of the eng/trans/adapter and...

    Help with difficult problem!!! ‘83 K5/4” lift/NP208 mounting height with incorrect homemade spacers vs correct spacers???

    Hello everyone! I have several unusual problems, not just mentally, but also with my ‘83 K5 that I’ve been restoring and am ready to install a new crate SBC350 and the original (rebuilt) 700R4 tranny and NP208 transfer case that I pulled out of the K5. When I got the K5, it already had a 4”...

    I called Summit Racing to have them confirm the PN’s of the OEM style oil press sender (that mounts close to the distributor) and OEM oil press switch (that mounts at the oil filter adapter) for my new GM crate SBC 350 to work with my factory 0-60 psi gauge. The photo shows the PN’s for my SBC...

    ‘83 K5/ SBC 350 Swap/ new/old oil sending unit differences/dash gauge/Autometer gauge?

    I'll go ahead and buy a factory style sender to install at distributor location connected to the tan wire to operate my factory dash gauge. I’ll also buy/install the oil psi switch at the oil filter location connected with the dk blue wire, the pink/WH wire and run the remaining wire to the...

    ‘83 K5/ SBC 350 Swap/ new/old oil sending unit differences/dash gauge/Autometer gauge?

    Additional info, the engine that came out of my ‘83 K5 was a ‘90’s Vortec 305. There was no oil press. switch installed at the oil filter location that was wired to the choke.

    ‘83 K5/ SBC 350 Swap/ new/old oil sending unit differences/dash gauge/Autometer gauge?

    Howdy y’all! I’m in the process of prepping my new SBC350 crate engine for installation on my ‘83 K5. I bought a new Autometer oil press gauge w/sending unit initially intended for my ‘73 Firebird but decided to use the new sender/gauge on the K5 new engine instead. The old sender was located by...
