Why should you buy Dart Blocks & Heads instead of a factory casting or other aftermarket components?
355-T6 aluminum provides 50 degrees more heat resistance and 5,000 psi more tensile strength than the more commonly used 356 alloy. It is denser and offers greater consistency because it contains no remelted scrap. No threaded inserts are required due to the inherent strength of the material.
Advanced casting technology enables us to produce heads with higher density and strength in the combustion chambers. Tighter casting tolerances allow profiled valve guide bosses to be cast in and produce smoother surfaces for improved flow.
All castings are qualified prior to machining to ensure consistency and are pressure tested after machining. A build sheet accompanies each block through the entire production process.
CNC Machining capability:
Dart's machine shop is fully owned; no processes are subcontracted. This provides total and immediate quality control. The size and quality of our CNC machining centers allow castings to be machined in fewer setups, reducing tolerance stack-ups. This translates into finished parts which are consistently superior out of the box and do not require expensive blueprinting after purchase.
Digitizing of optimized port profiles and combustion chamber designs with a coordinate measuring machine allows Dart to precisely duplicate these in a digital file. High precision Digital CNC machining centers then duplicate the optimal configurations, part after part, to ensure that every piece we ship is truly a superior quality product.
Dart products are researched extensively before production. Expert technicians and state-of the art equipment are employed to extract maximum performance while providing superior durability in our products. Development does not end when the parts go into production, however. We are constantly redefining our products to bring our customers the best performing components at incredible value. Dart's new custom designed and built wet flow bench is an example of our commitment to excellence. Capable of replicating the flow characteristics of a 600ci Pro-Stock engine at 10,000rpm, this one of a kind device enables us to analyze cylinder head flow properties in a whole new light. The result is redesigned ports and combustion chambers which produce significant increases in real world power.
Richard Maskin has a long history of developing powerful engine technology. His Pro-Stock engines have captured three world championships and numerous national wins. Together with a team of experienced and talented technicians, he continues to push the forefront of performance engine component design. A commitment to total quality and performance, coupled with leading edge R&D facilities and first hand racing involvement are combined to position Dart as the undisputed leader in aftermarket cylinder head and block design.
Dart's own Pro-Stock campaign as well as daily interaction with winning racers and engine builders enable us to constantly gain new knowledge and experience concerning engine performance and reliability.
We integrate these lessons to continuously improve our products; a "finished" design is never finished, we never rest!
Dart blocks and cylinder heads provide an exceptional value at an affordable price. Precision machining and quality control measures mean you get optimum out of the box performance. A "bargain" component can wind up costing far more after the machining which will be required to make it usable.
Dart blocks are loaded with features you won't find in any factory casting. Extra thick decks, siamese bores, enlarged water jackets, priority main oiling, 4-bolt main caps, finished main bores and cam tunnels, honed lifter bores, coated cam bearings and more.
Our cylinder heads offer considerable added value as well. Superior casting technology, premium materials, optimized port and chamber design, premium valve guides, hardened valve seats, rolled valve angles and CNC porting are among the available features. Fully assembled or bare heads can be ordered with combustion chambers matched to your bore size.
