PRI 2014: Survival Motorsports Debuts CNC-Ported FElony Head Design

We’ve worked extensively with Barry Rabotnick and his team at Survival Motorsports; he’s widely considered as one of the country’s leading experts on the Ford FE engine platform. In fact, he’s competed (with success) at the Engine Masters Challenge in the past using one of his company’s bullets. That development work has led to the company’s release of the FElony CNC-ported cylinder head design that’s been dyno-proven on the Engine Masters engine.

“These heads are designed to be used as bolt-on items for the 390, 427, and 428 engines. The port flanges are in the factory positions, which means that the heads are compatible with all of the popular intake manifolds and headers on the market,” says Rabotnick. In as-cast form, they flow enough air to make an easy 600 horsepower, and once the CNC-ported castings are selected, 700 horsepower potential with the right foundation is easily achievable.

IMG_4298Rabotnick tells us that the heads use the 16-bolt CJ exhaust pattern and work with all of the common rocker systems on the market. Bronze valve guides are installed and accept 11/32-inch valves, and hardened ductile iron valve seats are also standard.

In order to facilitate better performance, the intake and exhaust ports have been optimized to provide drastically improved flow. The heart-shaped CNC-machined chambers have the spark plug location shifted around to provide better combustion, allowing the end user to reduce timing requirements. The cylinder heads we checked out were the very first set of CNC-ported castings that Survival has put together; according to Rabotnick, this project has been over two years in the making. If you’re into making the FE platform perform, Survival Motorsports has what you need.
