How much horsepower does a Ford 408 stroker have?
The Ford 408 stroker engine is a popular high-performance engine option that can produce impressive horsepower and torque figures. Depending on the specific build and configuration, a Ford 408 stroker can generate anywhere from 450 to 600 horsepower or more.
What is a Ford 408 Stroker Engine?
The Ford 408 stroker is a custom-built engine that starts with a Ford 351 Windsor engine block as the foundation. The engine displacement is increased from the stock 351 cubic inches (5.8 liters) to 408 cubic inches (6.7 liters) through the use of a longer-stroke crankshaft. This "stroker" configuration allows for a larger displacement and greater potential for power output.
Factors Affecting Ford 408 Stroker Horsepower
The exact horsepower output of a Ford 408 stroker engine can vary widely depending on several key factors:
- Engine Internals: The type of camshaft, cylinder heads, intake manifold, and other internal components used can significantly impact the engine's power potential.
- Forced Induction: Adding a turbocharger or supercharger to the 408 stroker can boost horsepower output to the 500-600 hp range or more.
- Tuning and Modifications: Careful tuning of the engine's fuel, ignition, and other systems, as well as additional modifications, can further increase horsepower.
A well-built, naturally aspirated Ford 408 stroker engine with high-quality components can typically produce 450-500 horsepower. With forced induction and extensive modifications, output can reach 600 hp or more.
Advantages of the Ford 408 Stroker
The Ford 408 stroker engine offers several advantages over the stock 351 Windsor engine:
- Increased Displacement: The larger 408 cubic inch displacement provides more power potential compared to the 351 ci engine.
- Improved Torque: The increased displacement and stroke length result in greater low-end torque, which is beneficial for acceleration and towing.
- Aftermarket Support: The 351 Windsor engine has a large aftermarket, making it easy to find high-performance parts and components for building a 408 stroker.
Overall, the Ford 408 stroker engine is a popular choice for enthusiasts seeking a high-performance, large-displacement Ford V8 that can produce impressive power figures.
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 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.
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.
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.
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.
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.
How much power does a 426 stroker make?
Stroker 426-inch LS3 that Makes 638 horsepower!
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.
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.
