Choosing the Correct Block for Your LS Engine Build
Whether you’re scouring junkyards, ordering cores, investigating factory options, looking at aftermarket cast iron or aluminum blocks, or spending big bucks on billet LS blocks, you’ve probably noticed it’s been harder to find exactly what you want for the foundation of your LS build than it historically has.
Has it become more difficult?
As we’ve often written about in the pages of Engine Builder, and certainly in recent LS-focused issues, the LS engine family is still a hot commodity. The reasons are many and those reasons are valid. However, as that popularity has remained high from more and more people seeking an LS engine build or doing an LS swap or boosting a junkyard find, the availability of LS blocks are taking a hit. The result has been higher prices in some cases and longer waits in others, leaving people with a more difficult choice.

Going the Extra Mile with Cylinder Head Porting
It’s not just the port work alone that creates spectacular cylinder head performance. The most critical areas of a cylinder head are those which pass the most air at the highest speed and for the longest duration. Your bowl area, the valve job, the throat diameter, and combustion chamber are all crucial parts.
Tight Tolerances and Building Power
As you ascend Mt. Everest, you reach an area called the death zone. Once you climb high enough, the margin of error becomes perilously thin. That death zone also applies to engines. As the horsepower per cubic inch and rpm increase, the margin of error decreases.
CNC Update: Features and Automation
Precision is key when it comes to automotive parts; the complex designs of connecting rods, pistons and rings, blocks, cylinder heads, and other parts require super tight tolerances that are getting more and more difficult to be met by hand or with other machining processes outside of CNC.

Engine building is a segment of the automotive industry that has always been ahead of the curve in media blasting, and no matter the engine shop, cleaning equipment is a common bond.
