Haas Machine Company can offer full machine shop services for your antique, vintage, or muscle car or automobile. We can salvage or refurbish old and severely damaged castings and can offer you a low compression high performance solution for your restored engine, including high performance parts.


At Haas Machine Co. we've always prided ourselves on doing the highest quality machine work possible for all your everyday machine shop needs. But if you need antique work done on your engine parts, this is the only shop you should stop at. We service antique and specialty parts from a wide variety of vehicles, including:

  • Antique & Vintage Automobiles
  • Muscle Cars
  • Tractors
  • Military Equipment
  • Marine Craft

We specialize in salvaging and refurbishing old and severely damaged castings allowing you to make your engine and vehicle restoration numbers correct

Additionally, we offer a low compression, high performance solution that allows you to get the great performance you want for your restored engine while still using todays pump gas rather than the more expensive high octane gas. When performing this procedure, we use Prosis engine compression software in conjunction with four precise measurements of your engine cylinder volume to determine the exact compression ratio of your engine. Next we machine your engine and install the proper components to obtain the maximum compression that will still allow you to run pump gas. Many shops will tell you that they can sell you parts and perform machine work to get you a specific compression ratio, but unless they have your engine in their shop and take volume measurements, they are just guessing at it. At Haas Machine Company we don't guess about your engine because we know that a one-half point mistake in compression ratio is the difference between the high performing engine you want and a ruined engine you can't use.

Our expertise in this area is a byproduct of being in business for over 70 years. Due to the fact that many of our present machinists have been with the company for so long, they were able to work with former machinists who had been in our shop since the 1940's and passed on to them much of their knowledge and many of their skills. We also do extensive work on industrial engines, which have continued to use old time flat head valves and babbit bearing technology long after it had been abandoned in passenger and light truck vehicles, giving even more understanding and experience with older equipment. Since we work on these types of engines everyday, working on an antique engine is not a challenge for us. We routinely work on engines from the early 1900's while many shops have no idea how to work on an engine that is more than 30 or 40 years old. We also understand that many antique castings are in very rough shape, as they have been exposed to the elements or sitting for many years, and we have saved many of these old parts. We can:

  • repair many cracks
  • re-sleeve worn bores
  • make custom bushings and bearings
  • repair damaged threads
  • weld and repair valves
  • find modern parts that can be converted for use in antique engines

The above operations are time consuming and expensive, but with an antique engine the only alternative is to figure out how to repair it. We pride ourselves on saving engines and parts that many thought were beyond repair.
