How much horsepower does a Ford 408 stroker have?


The Ford 408 stroker engine is a popular choice among car enthusiasts and racers due to its impressive power and performance capabilities. This engine, based on the Ford 351 Windsor, is modified to increase its displacement to 408 cubic inches, delivering significant horsepower gains. But just how much horsepower can you expect from a Ford 408 stroker? Let’s dive into the details.


Understanding the Ford 408 Stroker


The Ford 408 stroker is created by increasing the stroke of the 351 Windsor engine, typically by using a longer crankshaft and larger pistons. This modification allows the engine to burn more fuel and air, resulting in greater power output. The exact horsepower of a 408 stroker depends on several factors, including the build specifications, components used, and tuning.


Typical Horsepower Range


On average, a well-built Ford 408 stroker engine can produce anywhere from 450 to 600 horsepower. However, this range can vary based on the following factors:



  • Compression Ratio: Higher compression ratios generally result in more horsepower, but they require higher-octane fuel to prevent engine knock.

  • Camshaft Selection: The camshaft profile plays a critical role in determining the engine's power curve and peak horsepower.

  • Induction System: Whether the engine uses a carburetor or fuel injection, as well as the type of intake manifold, can significantly impact performance.

  • Exhaust System: A high-performance exhaust system can help the engine breathe better, increasing horsepower.

  • Tuning: Proper tuning ensures that the engine operates efficiently and delivers maximum power.


High-Performance Builds


For those seeking even more power, a Ford 408 stroker can be built to produce over 700 horsepower with the addition of forced induction systems like superchargers or turbochargers. These setups are typically used in racing applications and require additional modifications to handle the increased stress on the engine components.


Conclusion


The Ford 408 stroker is a versatile and powerful engine that can be tailored to meet a wide range of performance needs. Whether you're building a street machine or a track-ready racer, this engine offers impressive horsepower potential. If you're considering a 408 stroker build, be sure to consult with experienced professionals to ensure your engine is designed and tuned to meet your specific goals.


Frequently Asked Questions

How much HP does a Ford 427 stroker have?


Torque peaked at 552 lb-ft at 4,800 rpm. The air/fuel was a bit fat, so a small jet change was made and then the engine was pulled to 7,000 rpm. Horsepower peaked at 597 at 6,600 rpm, and torque increased slightly to 556 lb-ft. A few more tweaks and we saw horsepower top out at 609, while torque rose to 561 lb-ft.



How much horsepower does a 408 Windsor have?


The 408 Ford Windsor Stroker engine was finished to have a 10.5:1 compression ratio, and was expected to pump out more than 550 horsepower on the dyno.



How much does it cost to build a Ford 408 stroker?


If you go with a stock block with a forged bottom end (crank, h-beam rods and pistons, internally balanced), AFR 205 heads, and all the fixens (air cleaner to oil pan using quality parts), it'll run you $9-10k for a 408/418. If you use a DART block, it'll be about $2-3k more, but you can go all the way to 460ci.



What's the most horsepower you can get out of a 351 Windsor?


Starting at 7 psi, the turbo 351W produced 631 hp and 608 lb-ft of torque, while stepping up to 10.5 psi brought 719 hp and 687 lb-ft of torque. The stock crank, rods, and pistons were all still in place, so we cranked up the boost to 12.6 psi—the 5.8L pumped out 790 hp and 776 lb-ft of torque. 01.



How much HP will a 408 stroker make?


530 hp
After installation on the dyno and a complete break-in procedure, the 408 was finally run in anger. Minor jetting and timing revealed peak power numbers of 530 hp and 534 lb-ft of torque.



How big is a 408 stroker?


You've probably already figured out from the title of our story that we're going with 408 cubic inches (6.7L), which is accomplished with a 4.030-inch bore and 4.00-inch stroke.



How much power does a 426 stroker make?


Stroker 426-inch LS3 that Makes 638 horsepower!



Can a 351 windsor be stroked to a 427?


In short, starting with a Dart 351W block, boring/stroking to 427 cid and utilizing a host of performance aftermarket components, we were able to build a streetable large-displacement “small-block” Ford engine capable of producing around 600 hp.



Why is a stroker engine better?


As its name implies, a stroker is where we increase engine displacement by increasing piston stroke. When we increase stroke, we take the piston deeper in the cylinder bore, which increases displacement. The longer the stroke, the greater the fuel/air charge.



What is a 408 Ford stroker?


The 408 Ford is an excellent choice for those looking for a Windsor based stroker engine to fit in place of an existing 351. The additional stroke provides a boost in power along with better throttle response, acceleration, and overall performance. Features forged pistons, hydraulic roller camshaft, and aluminum heads.
