Description:
NOTE: Photo set includes pictures of optional serpentine system
Are you looking to build an awesome restomod with great throttle response and all the power you can realistically put to street tires? Say up around 580 lb-ft of torque and 645 horsepower? Your ride is going to be a cruiser, so it needs to have street manners, be utterly reliable and low maintenance. Chances are your hood will be up a lot at car shows, so the engine needs to look great too.
Look no further. Borowski Race Engines has what you want. Our unsurpassed CNC machining capabilities allows us to build engines with power levels far beyond OE using the same foundation and leave them in the dust with better supplemental parts and improved designs. The signature Borowski valve covers have adorned many a top show and race car. Why not yours?
Let's look at three key elements of this build:
Short Block: A seasoned 6.0L GM LS crankshaft and engine block with 4.030" bores paired with forged rods and pistons (Callies/Diamond or Manley/Manley depending upon availability).
Top End: Our proprietary 600+ COMP hydraulic-roller cam controls the valve train and delivers good street manners street manners. You can go for "All-of-It" if you're looking for max power. The GM LS3 heads are CNC ported on our 5-axis, milled perfectly flat on our Berco and treated to a CNC valve job on our Newen. A Holley Lo-Ram intake manifold and 102 mm throttle body come standard. Other available intake manifolds include the & FAST LSXR and LSXHR.
An ATI Balancer comes standard if purchased without a serpentine system.
Here is a look at one on or dyno with the optional custom BRE serpentine system
AVAILABLE UPGRADES & ADD-ONS
Oiling Systems: These engines come equipped with a GM F-Body pan with an added baffle. A range of Holley 302-X retrofit pans are available to suit your specific requirements. One major available upgrade is a Dailey 3-Stage dry sump oiling system. These are great for motorsports applications as they deliver superior oiling performance, more horsepower and handling benefits (see blog).
Electronics: The available Holley Terminator X gives you true Plug & Play. No chassis dyno necessary as it comes with tune from our dyno and the unit is self-learning. The Terminator X will run your engine and can interface with the optional Holley Digital Dash to solve all your instrumentation issues. A Terminator X-Max can be selected for features such as tran control and drive-by-wire. FuelTech systems are also available.
Serpentine System: The most popular serpentines are black two-tones. We offer both the full range of CVF and our own BRE custom serpentines. The BRE's come with a 225 amp alternator so you won't run out of electrical power and can be selected with provisions for Hydratech hydraulic boost systems if needed.
The Hughes Performance 4L80e Muscle Car transmission kit comes complete with a torque converter that is custom-tuned for this engine and your vehicle. The kit also includes everything else you'll need for the install. This transmission can handle the power and will match up perfectly with the engine & available Terminator X-Max trans controller. The overdrive capability will make highway cruising a joy.
