Best decision I’ve ever made! The engine has made over 3100rwhp on a dyno, and an estimated 3400hp on boost at the track. We have had no issues of any kind. Maintenance has been very easy making racing much more enjoyable. No stress of the engine tearing up or worries of it not doing what is asked of it. I now own 3 engines from them in total with a fourth on the way. I have worked with 4 top known companies before ACE. My only regret is not doing it sooner! I highly recommend Stef and the crew.

ACE Racing Engines has changed our racing program into a winning success! From the first phone call to the finished product it has been awesome. Their attention to detail is like no other.

Ace is the best at doing things! They recently built me a Gen V LT engine for my 72 Nova and the results are absolutely incredible. The engine runs harder, makes considerably more power, is much happier from a tuning and RPM standpoint, and after 4 oil changes the filter looks completely perfect and the valve train stays put even at 9200+ RPM with over 40 psi of boost. Business is very easy with these folks and their pricing is very competitive to other shops, if not better! Top to bottom A+ experience!
Matt LaRue - Blacklist Performance
I can speak from experience with installing, tuning and winning with Ace Racing Engines for the last 4+ years. With almost a dozen different Ace complete engine combos I've had the pleasure of tuning every engine has been nothing but the best with crazy power on the hub dyno to some combos going in the 3 sec zone on small tires in 660ft. I highly recommend Ace Racing Engines!
