Testimonials

Ray Littlefield
Having approached a few local builders I quickly learned that nobody I approached offered warranty of any significance on rebuilt performance engines, but every single builder would do the work had I proceeded for a significant cost to me, all the risk being mine.
Ron Hall
In 2011 I was looking for a local engine builder down here in Australia to rebuild my old modified 302 cu in engine. What I wanted was my original Windsor block rebuilt with all new rotating parts and the heads either changed out for Alloy or modified to seek more power. I also wanted to understand the warranty such engine builders would offer. I also wanted good horsepower and torque.
Nicola Carrigan
I was looking for a Ford 351W engine to fit in a GT40 replica and came across Prestige Motor Sports on the internet. After reviewing other engine builders in the UK and overseas it was apparent that Prestige gave better value for money and had a reputation for quality. Doug Aitken was extremely helpful and always responded quickly to my emails and requests for information. I got what I wanted, on time, on budget and with no surprises. After my engine arrived Doug was helpful as ever when I was looking for compatible, parts, oils, etc. in the UK. My only regret is that I shipped the engine myself and it took forever; despite Doug's efforts to deal with my shipper. I should have let Prestige handle that too. I can thoroughly recommend Prestige Motorsports.
Humberto Freire
Prestige Motorsports did a GREAT job on my 1932 Ford Truck. From the custom paint job to the extras that make the truck stand-out...expert and custom work all around. They stayed true to the price estimates that I was given and continued to be professional throughout my experience. I would highly recommend them for all of your custom car/truck needs.
Steven Cowell
These guys are great very friendly. They built a big block chevy for me and it runs great. They helped me any time I called them with questions on the installation of the engine. They are always willing to take as much time as needed to help you get through any problems you may have. I will definitely purchase my next engine from them.
