The 427 Ford Small Block Stroker engine is by far our most popular engine combination. We offer several different versions based on the 351 Windsor. This 500 HP version is designed for street driving. Hard acceleration throughout the RPM band can be expected along with a muscle car thump that demands attention. Our 520 HP, 351 Windsor based stroker is our most popular street engine. Aluminum CNC ported heads allows us to use less camshaft than the 500 HP version and still deliver more power. You will see an increase in vacuum at idle and more power throughout the RPM range compared to the 500 HP version. Everything available from a short block to long block, turn-key carbureted or EFI and drop-in-ready with your pulley kit of choice. Turn-Key & Drop-In-Ready engine packages come dyno tested and every engine package is personalized for you & tailored to your ride.
