454-Equipped! 1975 Chevrolet K5 Blazer

Disclosure: This site may receive compensation from some link clicks and purchases.

Some classics are more than just a pretty face, which is undoubtedly true with this 1975 Chevrolet K5 Blazer. Its fresh paint helps it make a positive impression, but the mechanical upgrades set it apart from mere mortals. You must look carefully to locate a tiny badge that confirms that there is more to this classic than meets the eye. It is set for a new home, with the seller listing it here on eBay in Oklahoma City, Oklahoma. Bidding sits at $25,000, which is below the reserve.

The seller describes this Blazer’s combination of Santa Fe Tan and Antique White paint as “fresh,” but it is unclear when it underwent a repaint. The lack of apparent chips and marks suggests it hasn’t seen a lot of work since the spray gun was put away, with the vehicle presenting beautifully. The exterior exhibits a mirror shine and panels that are as straight as an arrow. There is no visible rust, with the seller acknowledging there are spots of surface corrosion on the underside. The bright trim and Soft Ray tinted glass appear flawless, adding to the positive impression. The factory 15″ wheels and trim rings show no evidence of issues and are wrapped in a new set of Cooper Discoverer tires.

This Blazer’s party piece is hidden under the hood, but it will make itself known the moment the driver floors the gas. The original owner ordered this classic with a 350ci V8, a three-speed automatic transmission, and power assistance for the steering and brakes. The small-block would have produced 160hp and 275 ft/lbs of torque, and coupled with the dual-range transfer case, would have made this Chevy an accomplished off-road performer. But who can’t do with more power? That was the question someone asked themselves when they pulled the 350 to slot in this 454ci monster. It is an LS5 version of the big-block, and the new owner can kiss goodbye to 160hp and say a big and bold hello to 356hp. That figure means that this Blazer should nearly rotate the planet on its axis in low-range four-wheel-drive mode. The person who installed the big-block performed the work to a high standard, creating a “factory” appearance that is admirable. The engine wears chrome valve covers and a matching air cleaner, but bolting on factory items would complete the illusion. There is no information on how this gem runs or drives, but the overall impression is positive.

The theme of spotless presentation continues inside this Blazer. The seats feature Beige vinyl covers that are spotless. The remaining upholstered surfaces are similar, while the carpet, dash, and pad show no signs of abuse or sun damage. The door pockets have succumbed to the typical sagging, but I have seen owners thread in elastic to address this shortcoming. The aftermarket wheel doesn’t appeal to me, but the seller includes the original in the sale. The factory radio has made way for an aftermarket unit, and the seller indicates the air conditioning currently only blows cool. They recommend a recharge to return the system to an ice-cold state.

Has this 1975 Chevrolet K5 Blazer ticked the right boxes for perspective buyers? The thirty-six bids submitted so far confirm that it has, and plenty of time remains for the bidding to climb from its current intense level to something akin to frantic. I won’t be surprised if that happens, but are you tempted to be part of the action?

    Wicked Blazer. Are the axles the 10bolts.. Can they handle the juice ?

      I wouldn’t think they would be a problems with the Blazer in the configuration it’s currently in. Bolting on a lift kit and installing the oversize tires that usually go along with it might be asking for trouble though.

      Should have a 12 bolt rear. And I think they still had a Dana 44 front axle in those years.

    It may look factory. But for what it’s worth, the biggest engine ever offered in the 1973-1991 K5 Blazer was the 400 4-barrel. Hopefully, the drivetrain is beefed up to handle the 454’s torque!

    These Blazers were notorious gas guzzlers back in the day. I cannot even imagine what this thing must get! Still, interesting build

      It won’t get 14 MPG on the highway. Around town, maybe 8 MPG. I had a 1990 K3500 Silverado and those are my mileage figures over a two year period.

    Wow! What a beautiful K5!! Love the yellow and white combo and tan interior! With a 454 and 3:73 gears it be fast off the line!! The dash gauges are done really nice. But would you go trailing with it? Or stick to pavement? I feel what’s missing up front are KC blazing lights with the covers(white )and big mudguards… It would be great to bring it to car or truck shows. Still can’t believe under 30,000 miles. I like to read the whole story about this K5. Reserve is going to be very high and with 5 days to go. They might hit it. Good luck to the next owner..🐻🇺🇸

    I really like these and this one BUT what is going on with that passenger side door alignment? Also, please slap whoever made the decision to put that steering wheel on this truck.

    I may be missing something here but I thought, 1973 was the last year for a full removable roof. I had a 73 and then a 79 that absolutely had a roof that met a cab roof. The 73 had the full roof/cap. I had that off many times.

      Hi John , 1975 was the last year for the full removeable roof, 76 had the half roof.

    Nice Blazer, but the engine isn’t the only non-original part. The hood and grill appear to be from a ’79 and the non-tripod door mirrors weren’t out till the ’78MY, I think.

    I had a 78 square body pickup 4×4, automatic,350 on a good day 8 mpg, I cant imagine what kind of mileage this beast would get. Nice blazer though.

    Dash panel has been reupholstered, the padding is plumper-looking than the original molded piece and you can see stitching which was absent from the stock piece.
