Description:
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 parts and leave them in the dust with better parts and improved designs (see machining videos at bottom).
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: A COMP hydraulic roller cam controls the valve train which features their BSR shaft rockers. This cam is pretty aggressive but we can switch that to milder one if you don't mind trading some power for better street manners. The RHS LS3-type heads have been CNC ported on BRE's 5-axis so they can handle the air flow from the FAST LSXR intake manifold and 102 mm throttle body. Other available intake manifolds include the Holley Lo-Ram & FAST LSXHR. If you're willing to give up a little power for significantly lower cost, we can swap out the new RHS heads for seasoned GM LS3 heads that we have CNC'd on our 5-axis, resurfaced and valve-jobbed on our Newen CNC.
This engine is rated at 645 hp and holds more than 500 lb-ft torque from about 3,900 to 6,600 rpm. Check out this video to see for yourself.
AVAILABLE ADD-ONS
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.
Serpentine System: Our custom serpentine comes 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.
