DESCRIPTION

The LS3 block is a great platform for a street cruiser, either naturally aspirated or with a moderate power-adder. The aluminum's lightweight relative to iron takes about 100 lbs out of the vehicle's front end. That makes a big difference in a lot of performance aspects. It not only changes the weight, it improves the weight distribution. Steering, braking and acceleration all benefit. Aluminum has better heat transfer than iron, which helps keep your engine running cool.

Downsides? The GM LS3 block costs a bit more and is not as mechanically strong as their iron block. In its sweet spot however, it's a great piece as you can see in the dyno video of the nitrous build we did a few years ago with this short block combination. Here is a link to the Engine Labs article: http://www.enginelabs.com/news/borowski-race-engines-builds-killer-ls3-nitrous-combo-with-video/

All the blocks we touch are finish-machined on our 4-axis Rottler CNC mill which boasts precision of 0.0002 in and 0.001 degree. Our Fentech computer balancer allows us to ensure that the rotating assembly is balanced to less than 1 gram-in deviation.

The one aspect of finish machining that we keep old-school is stone honing. We prefer the finish of the traditional stone hones over the modern CNCs using diamond cutters.

This (and all other builds we do) are assembled by skilled technicians with years of experience.

If you want to make power, you need to make sure it will hold together. Factory-style powdered metal rods, cast rotating assembly? Bad idea! You need quality-made forged parts like the ones lined up for you below:

Components:
- GM 6.0L LS block,
- Scat Pro Stock Series 4340 forged 4.000" crankshaft,
- Scat forged H-Beam connecting rods,
- RaceTec's AutoTec pistons (available flat top or dish),
- Custom Comp Cam that we will select to your exact needs,
- Cloyes Hex-A-Just Z Chain
- ARP Main Studs - The block's been align-honed with the new studs in place,
- Clevite H Series Rod Bearings,
- HX Main Bearings,
- Durabond Cam Bearings

We have CNC ported Dart Pro1 heads in stock that will turn this short block into your own personal screamer and have it delivered to your door in short order.

Please call us at 815-725-2727 if you'd like us to turn this into a long block or complete engine to your specifications.
