Have a restoration project? Bitner Automotive is dedicated to seeing your dream come back to life.

Our shop has the technology in-house to perform Ultrasonic Cleaning & Magnafluxing, Boring & Honing Balancing & Blueprinting, Milling of Heads & Blocks, Cylinder Head, Valve Seats & Guides, and Crack Repair. We can also update engine components to Unleaded Fuel Standards.


The cylinder honing process assures precision sizing plus exact Ra finish in every cylinder in any type block. Using our Liberatro XP digitally controlled balancer provides extreme accuracy, producing precisely balanced crankshafts. This ensures a very smooth ride – VIBRATION FREE. All engines are run on our in-house Dynamometer resulting in a trouble free finished product with maximum horsepower.


Not only can we dyno Chevrolet and Ford models, we have the unique ability to dyno such diverse makes as Chrysler, Pontiac, Buick, Olds, Sprint Car, AUSTIN HEALEY and FLATHEAD FORDS.


We charge $700 for one day of dyno testing with no fuel or ignition system set up. You can bring your own fuel or we can sell you Racing fuel.
