Custom engines from Modular, 5.0, 427 FE, even the Y-block, Duffee Motorsports can build a Ford engine to meet or exceed your expectations.

Our attention to detail, from planning the engine to precision machining to final leak free assembly, is what keeps the reputation of Duffee Motorsports as being one of the premiere high performance engine building facilities in Phoenix.

With a complete machine shop and the enthusiasm of Brian Duffee and Jeremy Measeles the sky is the limit.

Our interest in high performance automotive goes beyond engine building. We provide many other services mainly including (but not limited to) late model Mustang performance and tuning from mild to wild, Baer brake system installation, 9” third member set-up and assembly, fabrication, custom roll cage installations, and custom exhaust systems.

In many cases we have been approached by a new customer with a vehicle that has been modified with various bolt ons and power adders resulting in less than stellar performance. Our focus is working with the existing componentry to maximize performance and/or make suggestions that will enhance what they have already purchased. We spend as much time as it takes discussing with the car owner exactly what kind of performance he/she is looking for and then develop a plan that will fit within their budget.

We take pride in our accomplishments. Please have a look at some of our past, present, and future projects as they progress with photos, tech info, and dyno results.
