Rottler’s next generation 5-axis CNC multi-purpose machining center offers the precision and speed needed to reproduce cylinder heads with exceptional accuracy.
Now that Steve has everything setup in the 5-axis Centroid CNC, the real machine work has begun. Check out the progress on these billet aluminum heads.
As Steve continues to develop his SML engine platform, he gives us an inside look at the development of the cylinder heads, which start from a raw block of billet aluminum and turn into a work of art thanks to a Centroid 5-axis CNC.
Anthony and Elle Usher, veterans of the engine machining industry, have formed MEC CNC Machines based in California. “Our goal is to bring precision engine machining equipment to a broad range of customers servicing internal combustion engines,” says Anthony Usher. “Our clients rely on versatile equipment for manufacturing, modifying and rebuilding engines and related components.
Cylinder heads, as manufactured, are usually suboptimal due to design and manufacturing constraints. Porting the heads provides the finely detailed attention required to bring the engine to the highest level of efficiency.
How do you determine the proper cylinder head for your application, whether for street performance, racing, off-road or other? When selecting the appropriate cylinder head/runner volume, there are a few basics to focus on.
Choosing the “right” cylinder heads for an engine build can make all the difference in an engine that delivers and one that falls short of its potential. Horsepower, torque and throttle response all depend on how well the cylinder heads, camshaft and induction system work together. Choose the right combination and you’ll build a winner.
Edelbrock’s new Victor Jr. CNC cylinder heads are designed for high output 650+ hp Chrysler 426-572 HEMI engines. They feature fully CNC machined 170cc combustion chambers and seats CNC blended into cast ports for optimal performance. They also feature a 245cc intake runner volume and a revised exhaust valve angle to accommodate larger intake valves.
