About Us

45 Years of Precision, Performance, and Passion

At Schwanke Engines LLC, we’ve been building high-performance engines and restoring classic vehicles for over four decades. Our reputation is built on quality craftsmanship, technical precision, and a relentless commitment to helping our customers get the most out of their machines - whether on the street, strip, or show floor.

We own and operate a full-service performance machine shop, backed by a 5,000 sq. ft. showroom and performance parts department. Our facility is outfitted with top-tier equipment, including a Rottler CNC Bed Mill for block blueprinting and indexing, and a DynoJet chassis dyno to accurately measure rear-wheel horsepower and fine-tune engine performance.

Meet the Owner: Tim Schwanke

Tim Schwanke, founder and owner of Schwanke Engines LLC, started building engines out of a small farm garage over 40 years ago. With a deep-rooted passion for horsepower and mechanical precision, he grew the business from a one-man operation into a full-scale performance and restoration shop. Tim’s hands-on approach, technical expertise, and attention to detail have earned him a loyal following across the country - from drag racers to classic car collectors.

Whether he’s blueprinting a race engine, tuning a late-model EFI system, or overseeing a full classic car restoration, Tim brings decades of experience and personal commitment to every project.

Advanced Tuning & EFI Solutions

We specialize in GM late-model tuning using EFI Live, which allows us full control over the vehicle’s ECM for optimized performance, drivability, and fuel economy across different driving conditions. We also offer Flex-Fuel (E85) conversions, ideal for eco-conscious drivers and ag-based applications.
Note: E85 typically results in 15–25% lower fuel economy.

Restorations - From Classics to Custom Builds

In addition to engine work, we’ve been restoring classic and custom vehicles for over 30 years - from early Model A’s to 1970s muscle cars and today’s modern performance builds. Whether you want a full ground-up, turntable-quality restoration or a reliable daily driver or highway cruiser, we tailor each project to your style, purpose, and budget.
