CDP Technologies to Unveil Gaseous Fuels Cylinder Head for GM Engines


CDP Technologies LLC (CDP), the original equipment manufacturer (OEM) sales division of Crazy Diamond Performance Inc., says that it will soon be releasing an aftermarket gaseous-fuels-prepped cylinder-head package for GM 6.0 L engines.

According to CDP, the new and improved cylinder head can serve as a replacement or as an upgrade to an existing non-hardened engine for conversion to liquefied petroleum gas (LPG) or compressed natural gas (CNG).

Noting that the cylinder head is just one of the high-tech components in the upcoming CDP TorqueDrive engine, CDP’s new cylinder head has been engineered to incorporate higher airflow, strength and durability than the OEM unit. As reported, the CDP gaseous prep cylinder head includes ultra-high-strength stainless steel valves, proprietary hardened valve seats and revised seals.

Kevin Fern, co-founder of CDP, states, “The new materials that are now available help to improve performance, heat dissipation and have a high level of corrosion resistance. Our new cylinder head package will help fleets who have converted to an alternative fuel [CNG or LPG] maintain a long service life and will provide better performance than the OEM cylinder head. The CDP cylinder head package is direct replacement for the OEM unit, meaning that a fleet operator could replace a non-hardened or failed unit with no modifications to the engine.”

The company says its new cylinder head is manufactured from a high-strength rotocast A356T6 aluminum, noting that the rotocast process ensures granularity and reduces porosity.

Fern continues, “I’m confident that with these cylinder heads, which have eight percent greater airflow over stock, will significantly reduce the occurrence of valve seat recession, which is common when converting a gasoline-based engine to an alternative fuel. The CDP cylinder head package will include high-strength chrome-moly bolts and multilayer composite head gaskets. All of CDP’s engines will be equipped with this new cylinder head and allow our engines to perform efficiently and provide for high power than their competitive counterparts.

“CDP has also planned for a Compacted Graphite version of its cylinder head for its up-and-coming severe-duty 7.4 L engine,” he adds.

CDP will be releasing its new cylinder head for aftermarket use in the third quarter.
