We provide all your high performance automotive machining for your vehicle. From high performance street build-ups to Sprint cars. We have a number of flat track racers and drag racers as our customers too. You have seen our name mentioned in HotRod, Mopar Muscle, and Mopar Collectors Guide magazines! We can handle your job!

We use the parts you provide to your specifications. Or, we can provide the performance parts to meet any budget. Recently, we have done the machining work on a 6 cylinder diesel that has been converted to running on alcohol for tractor pulling competition! This former 360cid engine has been stroked to 800 cubic inches!! The final compression ratio is near 24 to 1 !! To give you an idea of the type of work needed on this custom built torque monster, here is a picture of the aluminum intake manifold:
This engine develops its maximum torque at only 2500 rpm!!!

Basically, if it's an internal combustion engine, we can build it any way you desire!!! Cars, motorcycles, or snowmobiles. High performance, all out racing, or a stout stock combination. We can machine and/or build it for YOU!

All machining on this B&M blown Flathead was performed here at Automotive Machine!!

Here is recent build on a 630 CID Oldsmobile Pro-Stock engine!

We are committed to providing you with precision engine machining and assembly utilizing state-of-the-art equipment from Sunnen, Serdi, Rottler, Rogers, and Ampro.

Stress Relief with Performance Coatings!!!

Generally, when modifying an engine for greater performance gains, the process usually increases STRESS on the parts. Along with our precision machining and high quality assembly, Automotive Machine offers a COMPLETE line of Performance Chemical Coatings. These coatings perform a variety of functions, but also they eliminate/minimize stress. A stress-free engine produces more horsepower!!

Now, in addition to our full line of internal coatings, we offer an external coating for exhaust manifolds and headers. The process will include degreasing and media blasting of the parts. Then an internal Thermal Barrier coating is applied. Next, two coats of "Cast Iron Gray" are applied to the outside of the parts. No more flaking paint, or rusting parts! And they look great as well!

The charge for this complete process is generally only $75.00 per side!!

Read on to learn more about Performance Chemical Coatings:

  • Thermal Barrier coating for piston domes, combustion chambers, valve faces, and exhaust ports.

  • Solid Film Lubricant coatings for piston skirts and pins, valve stems, rod, main, and cam bearings.

  • Oil Shedding Thermal Barrier for cranks, rods, and windage trays.

    Performance Coatings fall into four general categories. They are: Dry Film Lubricants, Thermal Barrier coatings, Thermal Dispersants, and Corrosion and Chemical Resistant coatings. It should be noted that some coatings will fall into more than one category. You might have, for example, a Corrosion Inhibitor that is a Thermal Dispersant. Also, we can use both a Thermal Barrier on the valve head, and Dry Film Lubricant on the valve stem. The treated valve is on the left!

    Dry Film Lubricants: Dry Film Lubricants, also known as solid film lubricants, provide a lubricating film that reduces friction, inhibits galling and seizing and in some instances can aid in dispersing heat. The appearance is generally a charcoal gray and takes on a sheen upon burnishing. They are slippery and provide an extremely low coefficient of friction.
    One of the obvious reasons for using a lubricating coating is to reduce friction, which improves wear, extends part life and frees up HORSEPOWER that is usually lost to friction. A second major benefit is a reduction in part temperature. This is especially important to such parts as valve springs! Here the pigment choice is critical as certain ingredients can trap heat in a part. Not all coatings are created equal!!

    Thermal Barrier Coatings: Thermal barrier coatings ( TBC ) are designed to reduce the movement of heat. In some instances, such as exhaust systems, you want to keep the heat WITHIN the part. In combustion chambers you want the heat generated by combustion to push down on the piston rather than bleed off into surrounding surfaces. Due to continued testing we are learning that simple thremal barrier action is not the only characteristic that is important. In fact, certain TBC's will move an engine into detonation! TBC coatings can be made from a variety of materials. Ceramics get the most attention, though there are other materials that are superior in specific applications. The proper choice is critical to the overall function of the part! And here at Automotive Machine we can make the proper choice for your application!!

    Here we have a pair of Diamond Ultralights pistons that have been treated with both a Thermal Barrier Coating for the crown, and a Dry Film Lubricant for the entire skirt area!!

    Thermal Dispersants: Being able to move and control heat is of tremendous importance. Excessive temps can lead to metal fatique, boiling fluids, damaging metal expansion, reduced electrical efficiency and a host of other problems. Traditionally dealing with heat has been handled either by expanding the radiating surface, constructing parts from materials that are more heat conductive, and using the color black. With advances in thermal management methods, additional ways of enhancing heat transfer now exist. Individual products such as TLTD can be utilized by themselves or in conjunction with other coatings to manage the flow of heat. TLTD is capable of transferring heat FASTER then the bare metal surface. While TLTD does make use of the color black, TLTD is more than a simple "black body" heat emitting coating. TLTD includes ingredients that also contribute to increased heat flow. Combining these properties with increased corrosion protection and the thin film application technique, maximizes thermal transfer capabilities. Effective on brakes, intake manifolds, cylinder heads, oil pans, radiators, intercoolers, and .... MORE!!
    Certain TECH LINE Dry Film Lubricats are capable of reducing part temps not only thru the reduction of friction but also thru increased thermal flow. The active ingredients accelerate the movement of heat. This is especially beneficial on valve springs where excess heat can lead to accelerated fatique and breakage!

    Corrosion and Chemical Inhibitors: The loss of effectiveness, reduction in part life, and deteriorating appearance due to corrosion/chemical damage is of real concern. Losing a well machined/tuned header to rust is not only expensive, but frustrating. A good aluminum intake manifold can become junk if the water inlet area corrodes excessively. Keeping components clean and attractive is of concern when promoting your vehicle! TECH LINE offers a variety of protective coatings that also enhance the appearance of a part. Many of these coatings will have the additional benefits such as Thermal Barrier or Thermal Dispersant capabilities.

    is an exclusive agent for TECH LINE coatings. Let us coat your parts to give you these benfits:

  • Increased Horsepower
  • Increased lubricating protection
  • Reduce friction
  • Reduce part temperature
  • Increase combustion chamber efficiency
  • Reduce detonation
  • Oxidize fuel more efficiently
  • Shed carbon
  • Keep heat in the combustion chamber
  • Disperse heat from intake/exhaust manifolds, heads,oil pans
  • Reduce thermal transfer into intakes, heads, and brake parts
  • Reduce corrosion and chemical damage
  • Reduce fuel separation and drop out
  • Increase port and exhaust velocity
  • Extend part life via reduced stress

    But what POWER benefits are there from this process????

  • Increased exhaust gas velocity
  • Reduce Carb air inlet temps
  • Reduced intake manifold temps
  • Reduce fuel drop out
  • Reduced heat transfer to incoming air/fuel charge
  • Increased flow thru ports

    This should allow you to make effective changes in timing, clearances, and jetting to develop OPTIMUM PERFORMANCE!!
    According to dyno tests on a 355cid Chevy engine, you can expect a 10hp gain just from coated pistons!! Maximum GAIN for a completely coated engine developed 68HP more over a broader powerband!!! Imagine your race engine already employing ALL the usual enhancements and performing at peak HP. Now, just by PERFORMANCE COATING vital parts with the proper coatings, you can gain an additional 68 HORSEPOWER!?!?!?! This could be the "edge" you have been looking for!!!
