The attention to detail, accuracy and performance required to develop World Record Breaking Race Engines, that will last, takes the micro focus of one extensively trained engine builder. Ray Little is that man. Ray Little is the ONLY engine builder here at Raymac Racing Engines. This limits the engines we do become involved in but our success, performance and longevity of our products speak for itself. We refuse to allow inexperienced hands involved in something so important as your race engine!


Family Owned and Operated


We are a family owned and operated business. Based out of Mansfield, Texas. Some of our specialties are large power adder pro-mods, endurance engines, circle track and road races, LS based ultra performance street/race engine building.

We have also developed a line of street, hot rod, industrial/agricultural "Dura-mac" engines. As a result of 30 years of research/development and partnerships with manufacturing companies we have accumulated an extensive supply of cutting edge (Redeveloped by Raymac) parts and components. Our prices can't be beat and the level of quality and development put into each part is something you won't find anywhere else. 

After months and sometimes years of research our partner manufacturing companies, under the advise of Ray Little, remanufacture these parts to a new level of performance. As a result of our assistance to the manufacture we then use these parts to create our World Record Breaking Motors. 

We sell race parts at wholesale prices direct to the public!!

Blast from the past. Love finding old articles on our customers:

"Quickest Diesel
Greg Hogue, Aledo, TX, ’03 Dodge Ram 2500

A lot of cars were tuned rich for safety’s sake, but none of them could match the smoke show of this Ram with a hot-rodded 5.9L Cummins diesel. Working with Diesel Power magazine’s David Kennedy, the oil-burner ran as quick as 11.84! Not bad for a truck that had 210,000 miles on it when they started the buildup. It finished 14th with a 12.03 average
Power Combo: The stock 5.9L Cummins has a Raymac Racing Engines cylinder head (it’s a straight-six), a Bullitt cam, and a Nitrous Express two-stage progressive system. It makes 860 hp at 2,900 rpm and a completely stupid 1,648 lb-ft of torque at only 2,200 rpm.
Best E.T. and MPH: 11.84 at 110.05 mph"
