I installed a Prestige Motorsports 408 stroker engine in my 1990 Ford Bronco. So far the engine appears to be a very good replacement for the 351 Windsor engine. It has plenty of power but not so much that it stresses the stock drive train and it hasn’t leaked a drop of oil. It’s been a real pleasure dealing with Doug, Shawn and the actual engine builder, Senior. They were always available to answer any questions I might have and work with me any way they could to help me complete my project. Thanks guys, keep up the good work.
Steve & Kate Jungwirth
I stumbled onto Prestige Motosports when seeking options for a replacement engine for my cruising/show van. I emailed Doug and Sr and we decided on the Ford Small Block 408 Stroker package. On top of the initial package we added a multi port fuel injection intake manifold and Holley Terminator X ECU. It was difficult to find an oil pan to fit my application that was suitable for this build. Doug was able to find an oil pan that would fulfill the needs of the engine and had his fabrication team modify the front sump. The modification worked and the pan cleared the cross member and still looks great as natural steel. I don’t have the engine totally installed yet, but from the pics I have posted it has received many compliments. I will post again once I have the van back on the road and am able to review the final product.

In the future I will travel to the USA to buy a corvette from 68-72. Do not hesitate to buy a 383 crate engine 500hp😍 ... GREAT PROFESSIONALS !! 🏁🇺🇸👍
Johnny Barb
Doug and Seinor and the whole crew are wonderful to work with. There service after the sale is amazing. My client has had several builds from them and anytime I have ever had questions they answer right away or call you back same day. Their engines with the warranty are hard to beat unlike dealing with Summit or Jegs where your dealing with a third party. Great work guys 👍
Flynn
I had my first encounter with Prestige Motorsports a few week ago. Doug and his crew came highly recommended by a respected member of the hot rod community so I figured I would give them a try. WOW!!!! I have to say that my experience was first class. I was in the final stages of installing a Borla 8 stack injection system in my 1964 Corvette and had no idea how to set up the Holley Terminator X system. Doug worked with me until the entire system was up and running. The questions that I had along the way were answered with a high level of expertise and not to mention quickly. I can say with all sincerity that I will recommend Prestige Motorsports to whomever asks. GREAT JOB!!!!!
Matthew Lapides
This is a first-class team! There are plenty of motor builders, but Prestige set themselves apart from competitors from intial discussions to crate delivery. The team is very knowledgeable, provided amazing advice, and put together an awesome 351 Windsor Stroker (427 cu in) with a Borla intake system at a fair price and attention to detail. They kept me informed during the build with images and videos, and even provided a live video during the dyno tune with all of the particulars. The crate arrived in great order with all accessory items securely mounted to prevent damage. They made a complex decision easy, and had my confidence from start to finish. You all rock! Thanks for the great work and service.
Thomas Williams
From start to finish I couldn’t be more happy with the service from Doug and his team! I popped in almost unannounced on vacation and they welcomed me in like family to see their operation, needless to say I was impressed! Got my dyno video today and the numbers are even better than expected! 6 out of 5 stars in my book! Thank you Doug and team!
Jay Stone
Prestige has some of the best front end and back end service that I have experienced from any company. Doug is awesome to work with and learn from, they deliver exactly what they promise and the build quality is top notch. I can't wait to do it all over again with another project.
Melvin Murphy
Don’t know where to start but I can say they are one of the best in the business of custom tailor-built engines. I live in California so I was a little nervous having a motor built so far away but after talking with the sales rep and frequent calls from the owner Doug made me trust this company a lot more. They always gave me updates from start to finish. I never called once because of worry, they would call first lol. I couldn’t be happier with the power my motor is putting out and the craftsmanship is second to none. Everything looks beautiful and even better in person. Thanks Prestige Motorsports for the great service and quick delivery. Will be doing business with you again!
Bobby Yenke
Great service and my 363 short block turned out awesome
Jose Uriarte
I would like to share my very positive experience I had doing business with Prestige Motorsports. First of all during my initial seeking out of companies that would build me a custom 460ci small block I found Prestige Motorsports. I chose them because of the nature of my build and how they were perfectly happy to build the kind of motor I wanted and built the motor around my needs and wants. a truly custom build. They truly delivered, 667HP 460ci small block ford is what I received with a 3 year unlimited mile warranty. Sounds crazy but that's the warranty Prestige has for their engine builds. The reason for my review is the exceptional customer service i have received by Doug "the owner" after my engine was received. He was on the phone with me during my initial startup and has spend his time on the phone with me on numerous occasions dialing in my tune and making sure my car is running tip top. I would highly recommend Prestige Motorsports to anyone looking for a new engine for their project car. Also Doug has replied to any text or email even if it doesn't have to do with anything directly involved with the engine build. So all in all I am very happy with Prestige Motorsports.

Looking for quality? This is your go-to team.
Mike Kelly
They know what they are doing!!
Vance
These guys did an awesome job not only building my 427sbf they met the deadline I needed for a show coming up! They also delivered 30 more horses and a little over 15 more foot lbs of torque then expected. In all I would recommend prestige motorsports to anyone looking to do a engine build! I'm a very satisfied customer!!!
William Roberts
Very professional staff. Kept me up on every aspect of the engine build. Visited the shop and was amazed at the quality of their workmanship of not only their motors but also their car restorations. Called Doug several times and he was always very helpful. If you want it done right, take it to Prestige Motorsports.
Steve Schilder
Contacted Prestige about getting a motor built for my boat. Questions about my needs were very pointed and on topic. This made me feel very comfortable dealing with them because they didn't want to sell me the wrong product. I was kept up to date during the entire process up to and including emails, pictures and videos. The engine arrived in the crate with everything required to be a turn key unit upon install. I highly recommend this great group of guys to everyone I talk to. I will be using Prestige again in the future when my Chevelle is ready for it's motor.
Jerry Magilton
I can't say enough about Doug and his team. They have truly made this a great experience. They used their in-house heads and cam to make a 520HP 427 Windsor Stroker that is poised to write checks that the rest of my 67 mustang may not be able to pay!!!! My inner 12 year old is euphoric!!!
Thomas Anderson
I ordered an all-aluminum all Shelby 427ci 351 small block 8 stack fuel injected engine & Tremec TKX transmission complete package for a CSX 9000 Shelby Daytona Coupe. I can highly recommend Doug & the team at Prestige Motorsport. Any small aesthetic change that I made along the way (there were indeed a few) was absolutely no problem at all & everything I requested was promptly replied to & just as promptly administered. My experience was extremely positive & every facet of Prestige Motorsports customer service & attention to detail was absolutely of a 5-star gold standard & very professional at all times. I am extremely happy with the result & am looking forward very much to posting my own video when the Daytona is complete. Again, I cannot recommend them highly enough!
Malcolm Viles
I'm not sure I can say enough good things about Prestige. I had a very good experience with them years ago when they were just starting and went back to them recently to solve a 2 year old problem I had with an EFI installation on my 1970 Camaro. Needless to say, I was frustrated and had engaged 3 other tuners. None of them solved the problem but Doug was able to diagnose the problem based on my description. Once I'd corrected the small exhaust leak, he tuned the car remotely and my 2 year frustration was over. The car is running better than it ever has!!
Russell Jones
Extremely knowledgeable and very responsive. Always took time to thoroughly listen to and answer my (many!) questions. I will be very proud to have their work powering my vehicle, one that I have waited 30 years to acquire.
Paul Broni
Excellent service and wicked engines!!
David Pieri
I recently purchased a BDR 427 Shelby Cobra that was equipped with one of Prestige's engines, and I was just thoroughly impressed with the info in my USB card that came from Prestige, showing video and tech of the actual engine, including the dyno run/info, break-in procedures, and all mileage "check-up" procedures afterward. Top notch. Thank you!
Pablo Mazlumian
Prestige built me a Dart 427 for my Corvette. They are extremely professional and knowledgeable. I’ve reached out several times during and after the build. They respond quickly and are very respectful. No question went unanswered, and they do incredible work. Their motors are professionally built with all the proper documentation to correspond with your build. I highly recommend Prestige Motorsports to anyone looking to put street-able power down!
James Santefeumio
Doug, Shawn and the gang at Prestige did an awesome job building my 427 small block for my new Cobra. Went with Borla for the added touch.These folks are very responsive and willing to help or answer any questions quickly.
Brad Cullen
That being said, I found Roush to be extremely unresponsive. The exact opposite of the kind of customer service you would want one buying a motor of this nature. So I began exploring options and came across Prestige. The more I researched and then the more I spoke with the guys at Prestige, the more comfortable it became. They are everything you would hope for when building a motor. Precise and prompt communication, plus under committing over delivering in terms of timeframe. But most importantly they built an awesome motor and sent me detailed communication during every step of the process. The motor is now in the car and it’s an absolute beast. Additionally, their warranty is far superior to Roush. In the end I got a motor with more power and a better warranty in a company that I enjoy doing business with.
