For sale is my 1994 2 door Chevrolet Blazer with 129,130 miles. It was originally white but was painted satin black before I bought it. These trucks are popular due to their reliability and proven performance and parts are easy to find. When I purchased the truck in June of 2013 it had 101,625 miles. Since then, I've taken good care of the truck and replaced many parts, including completing an 'LS' engine swap in 2021. It's been garaged and driven primarily on weekends since fall of 2020.


The engine, an all-aluminum L33 or VIN 'B' (a factory high output LS engine), is from a 2005 GMC Sierra with 51,684 miles, and is controlled by a Holley Terminator X ECU. It has a mild Comp Cams XFI RPM camshaft and upgraded LS6 valve springs. Combined with shorty headers, this gives the truck a bit more character over an otherwise stock engine swap, but it retains good driveability, fuel economy, and road manners. The aftermarket Holley ECM runs two electric fans, and the swap included a new alternator, water pump, and power steering pump. I also went ahead and replaced the brake and fuel lines with stainless lines. I've kept the aftermarket Centerline wheels and there's lots of tread left on 33x12.5xR15 tires. 

 

Otherwise systems are stock or have been replaced with Genuine GM parts. This includes the front suspension and steering, front and rear brakes, and fuel tank. The truck does retain the stock air conditioning compressor which is still controlled by the stock computer.

 

The truck runs and drives great, thanks to the more modern engine than the original throttle body injection-based L05 350. Based on logged data from the Holley system, the engine is producing around 350-360hp and achieves 18 mpg cruising at 70mph. It pulls strong off the line with 3.73 rear gears and the 5 speed NV3500 manual provides wide ratios for both pulling and a low overdrive. It has a clear title, no accident history, and a current DC emissions inspection through July 2027.

 

The tape deck slot is filled with an amplifier. A 1/8" stereo mini jack utilizes the tape deck input as an aux input mounted in the driver's cigarette ash tray. The radio works fine but the display does not work. The stock dash gauges all work using the stock engine sensors and computer, but the temperature gauge went dead last year. The Holley ECU drives the tachometer and is programmed to light up the check engine light if the coolant temperature gets too high.

 

The truck does not currently have its front prop shaft, differential, or CV joints installed but the sale includes these parts, as well as the original spare tire and underbody skid plates. The interior headliner has started to sag above the front seats and the rear wiper does not work.

 

The swap uses as many stock parts and connectors as possible, for either the 1994 or 2005 truck. More detailed parts/swap breakdown (these are the parts that are NOT stock for a 1994 Chevrolet Blazer):
