Building a Pro Touring car is about balance—combining classic muscle with modern performance, reliability, and drivability. One of the most important decisions in that equation is the engine. The heart of your build determines how it performs, feels, and even sounds. Choosing the right powerplant is both a technical and emotional decision—and at CPD, we believe it should reflect the purpose of your build, not just the horsepower on paper.
Below, our team breaks down what to consider when selecting the perfect engine for your Pro Touring machine.
1. Define Your Build Purpose
Before you start comparing horsepower numbers, think about how the car will actually be used.Ask yourself:
- Will this car see daily driving or weekend track days?
- Do you want high-revving excitement, big torque, or both?
- Is reliability and serviceability your top priority—or ultimate performance?
2. Choose Your Engine Family
For most modern Pro Touring builds, the choice comes down to two proven families: Chevrolet LS/LT or Ford Coyote/Modular powerplants. Both have their strengths:Chevrolet LS / LT Engines
- Compact, lightweight aluminum architecture
- Massive aftermarket support and parts availability
- Affordable power potential and tuning flexibility
- Ideal for swaps in classic GM and even Ford chassis
Popular Options:
- Blueprint Engines LS3 or 427 LS7 — excellent all-around performance
- GM Performance LT4 — supercharged efficiency with OEM reliability
Ford Coyote / Modular Engines
- High-revving dual overhead cam design
- Excellent throttle response and naturally aspirated sound
- Ideal for Ford restorations and restomods (Mustang, F100, Falcon)
- Slightly taller packaging but unmatched modern performance
Popular Options:
- Gen 3 Coyote 5.0L Crate Engine — proven 460+ HP platform
- Predator 5.2L Supercharged V8 — next-level performance for advanced builds
3. Consider Power Goals vs. Chassis Capability
A 700+ horsepower engine might sound tempting—but unless your chassis, suspension, and braking systems can match it, that power is wasted (and unsafe). Pro Touring is about usable, balanced performance.CPD recommends:
- 450–550 HP for street-driven builds (comfortably balanced with handling)
- 600–700 HP for high-end Pro Touring and autocross builds
- 700+ HP for track or showcase builds only with supporting systems (IRS, big brakes, aero, etc.)
4. Match the Engine to Your Transmission & Rear Gear
Every engine has an ideal RPM range where it performs best. Pairing it with the right transmission and gear ratio ensures power delivery feels smooth, not strained.- Manual builds: Match cam profile and gear spacing to maintain midrange torque.
- Automatic builds: Choose torque converters that match stall speed to your engine’s curve.
- Rear gears: Generally, 3.55–3.73 ratios are ideal for most Pro Touring setups.
5. Think Ahead on Cooling, Clearance, and Fitment
A modern powerplant means modern demands: tighter tolerances, higher compression, and more heat. Ensure your chassis can handle:- Proper radiator and fan setup
- Clearance for headers and oil pans
- Updated fuel and electrical systems
- ECM/PCM mounting and tuning space
6. Partner with Proven Brands
Choosing your engine is also choosing the company behind it. That’s why CPD only works with brands that meet our standards for performance, support, and reliability:- Blueprint Engines – trusted crate power with dyno-tested precision
- Wilwood Disc Brakes – to stop what your engine starts
- Royal Purple – premium synthetic oils to protect your investment
- Forgeline Wheels & Velgen Wheels – where power meets the pavement
