408 cubic inch Windsor stoker kits are based on the 4.000 bore 351 Windsor engine block and a 4.000 stroke crankshaft. They are a perfect replacement for the 351 if you want the increased power and torque you get from a larger engine. Street engines will require a 72cc combustion chamber to keep compression ratios in the 10.25:1 range. Aftermarket cylinder heads and larger camshafts are a good addition to complement the increased capacity. Custom combinations are also available for specialized applications.
Flat Top
Flat top pistons in a 408 Ford engine will generally provide compression ratios in the 11.5:1 (61cc head) range which makes them a good option for engines with aluminum heads and larger than stock camshafts. They also work well in heads with larger combustion chambers. Valve reliefs are configured to work with most types of standard and aluminum cylinder heads and will normally fit camshafts to slightly over .600 valve lift.

Villain - Cast Crank, through-bolt rods, forged pistons, designed for stock replacement and mild performance applications.

Vigilante - 4340 Forged Crank, I-Beam rods, forged pistons, designed for Street or Street and Strip performance applications.

Vindicator - 4340 Forged Crank, H-Beam rods (ARP-2000), custom forged pistons designed for serious Street or all out Strip applications.

Vanquisher - 4340 Forged Crank, H-Beam rods (ARP-2000), custom forged pistons designed for serious Street or all out Strip applications. All components are Made in the USA.
Dish Top
Flat top pistons in a 408 Ford engine will generally provide compression ratios in the 11.8:1 (61cc head) range which makes them a good option for engines with iron and larger than stock camshafts. They also work well in heads with larger combustion chambers and boosted appliations. Valve reliefs are configured to work with most types of standard and aluminum cylinder heads and will normally fit camshafts to slightly over .600 valve lift.
