LS1 V8 Power: 2003 Chevrolet S-10 Blazer Xtreme

The second generation Chevrolet Blazer/GMC Jimmy/Opel Blazer was based on the popular S-10 truck chassis and was now midsized to match the growing wasteband of 'Murica.  The biggest engine available from the factory was a 4.3 liter Vortec V6 that produced up to 200 horsepower, so if you wanted the relive the lunacy of the Typhoon era, you'd have to swap in something with more thrust, like an LS1 V8.  Find this 2003 Chevrolet S-10 Blazer Extreme with LS1 swap offered for $7,000 in Woodstock, CT.  Tip from Art.

The Blazer was a simple mid-sized SUV that offered a 2-door family experience for folks who lived in inclement climates or wanted a high-up seating position.  The Blazer was a precursor to the modern crossover SUV, but was still truck based and could climb if needed.  If you didn't need the offroad capability, the 2WD version offered a better road experience with less weight and complexity.  

This Blazer started life as a V6 powered Xtreme package (the successor the the SS) but it is now powered by a 5.7 liter LS1 V8 from a 1998 Pontiac Trans-Am.  The seller claims 304 horsepower at the ground, so it should make for an extreme SUV experience.  For the price of the engine swap (if you paid someone else for labor) this seems like a great deal.  It even passes the local CT emissions test.

 See a better car for your wife to drive everyday?


  1. Nice clean swap, good looking vehicle. Not sure how long the trans and rear end will last with the extra power of the LS motor. Maybe you can beef up the transmission internals to handle the power. I'm liking this swap, seems like a reasonable price for what you get.

  2. Almost worth it just to use that Cobra snake shifter setup he has going on there and not to mention its running 315's out back? This thing is awesome! My pops has the stock version of this truck and its nice but seems so goofy, all skinny legs with wide hips, always kinda clunky and goofy around town. I wonder how this thing feels to drive around town nicely and how it feels when letting the snorting V8 lump get angry? That's a first year Fbody LS1 motor so its ecu is less desirable with lower resolution, etc. but its still a rip snorting good time of a swap, might have been upgraded during swap, not many details. Nice price I must say!

  3. I think the shifter need to call a physician. It's not supposed to last for more than 8 hours.

  4. Haha just caught the plates...321 CYA...LOL

  5. I would like to see this thing. Another 100 horses shouldn't be to to much for most suspension and drivel line parts to handle. I guess the donor car was an auto or he might have done the whole package. If I wasn't 7000 miles away I might give this a good look over, I think it could serve my purposes very well.
