Testimonials

 5/5

But beyond the stats of the motor Doug and his team spent plenty of time talking me through the options and weighing the pro/cons of each to help create a motor set-up that I would be happy with for my intended application (mostly street with a bit of track time). He also set up the transmission and clutch for the motor and is helping me drop all that in to my chassis as I trailered the chassis over to his shop since I only live about 2hrs away. Great team and a fantastic level of service and support.

I have had a fantastic experience with Prestige Motorsports and can't hardly recommend them enough. Doug and his team (Thanks Sr.) put together a 427 Ford Windsor block based crate motor with >525 hp and >540 ft/lbs of torque with >500 ft-lbs of torque from 2800 all the way to 5400 rpm to go into my cobra kit car.

Thanks Guys! I would recomend you to anyone, also more cost effective than some of the other builders for the same spec.

Excellent service, Doug kept me up to date all the way through the build and interfaced with my shippers to export it to South Africa, the engine is fantastic delivers the driveabilty I asked for but still with 500+hp.

First and foremost I can't express the professionalism and honesty from the guys at Prestige. The timely manner in the build of my motor very impressive ( motor at my door within four weeks). This is the first motor I have ever had professionally built and had numerous questions and Doug was always willing to take the time out of his busy schedule to answer them. ( Even contacted him after hours and he responded) A big plus for Prestige is there ongoing commitment to satisfaction coming from there buyers. Believe me when I say there just not a company who sells you a motor, there way more than that. Even after I got everything installed Doug said " if ya want bring your car up we can fine tune it " I made those arrangements and Doug and the guys were there and immediately got me in and went over everything and made some suggestions on some changes I may want to consider. I left Prestige with a huge smile. Again the professionalism is top notch.not sure about you but for me a business that does what they say they there gonna do when they say there gonna do it is a business I'll travel to do business with. Thanks again to the guys at Prestige !! 150% SATISFIED!!!!
