The name might be new, but the history behind ACE goes back over 50 years.  What began in 2011 as Richie’s Nostalgic Auto Parts has evolved into a one-stop shop for cast and billet aluminum early domestic engine components.  Frank “Richie” Richards created his very first part – a small two barrel scoop – in 2011, and grew his line to seven different scoops/air cleaners, plus a variety of Chrysler Early Hemi, Chevrolet, Buick Nailhead, Ford Y-block and Pontiac valve covers, valley pans, timing covers, manifolds, fuel blocks, tank brackets – and more.  After acquiring many original Mickey Thompson (“M/T”) and “Parker” patterns and molds, Richie was able to expand his lineup with historical, period-correct items – and Drag Master’s popularity grew! Now under the capable ownership of performance aftermarket industry veteran Nick Arias III, ACE’s goal is to continue Richie’s legacy of high-quality components and exceptional customer service.

About ACE’s owner, Nick Arias III

Being raised in a high-performance environment, it was hard not to appreciate the beauty and intricacy of aluminum castings.  From my earliest memories of two Hemi-powered top fuelers push starting towards the line at Lion’s Drag Strip – then marveling at their thundering, smoky, ear-splitting pass down the 1320 – the M/T valve covers, Scott injectors and Delta blower drives are what stood out most on these creations.  Their beauty and functionality left an lasting impression.  With ACE I now have the ability offer similar cast parts. Also, by spending a lifetime at my family’s businesses – ARIAS Pistons and ARIAS Racing Engines – and the 50+ years’ of mentoring by my Dad, Nick Arias Jr., I’m able to extend the experience gained by designing, manufacturing, and application of cast, forged and billet engine components.  It’s my guarantee…you’ll be getting the bitchin’-est parts and pieces available for your Hot Rod!
