SD Concept Engineering Means Big, Reliable Power
Why pay the same price for a boring "crate" motor when you can get something unique for your money? We meet your desired performance goals with SDCE Engine packages that are individually hand-built to order, utilizing the best-suited components for your specific application and our extensive background in performance engine design.

Each SDCE Engine receives the attention to detail that you will never see in an average over-the-counter “assembly-line-built” crate motor, allowing us to build Untraditional Power in Untraditional Ways!
Put Our Experience to Work for You
Our philosophy is if you understand how an engine works, it makes no difference what the badge on the front of the car says. From vintage Mopar, Ford & GM to modern day engines, there are things we’ve learned as engine developers that sets us apart from the average engine "assembler.” With years of hands-on engine building know-how and our way of thinking outside the box (rather than following the herd), dollar for dollar SDCE’s engine packages will out-perform the competition.

Fully Tested & Documented
Engine development and testing occurs in real world conditions on our engine dyno. Every engine that we produce is dyno tested before leaving our shop. For customers who choose to have us install their new engine, further tuning on our in-house chassis dyno is performed. Street & track tuning is also available.

Each SDCE engine comes with full documentation including but not limited to assembly sheets listing every part and piece installed in the engine, clearance sheets, balance sheets, head flow sheets and dyno sheets.

As a testament to the durability and longevity of our engines, our 1400HP Challenger has had the same engine in it for over 7 years now. Against what many people think and believe, our engine is a STOCK block and crank from a vintage 1960’s era Mopar.
