Welcome to Ford Six Performance!

The Web's Leading Resource for Ford Inline Six-Cylinder Engines and Cars!

FSP Mission

This site is for enthusiasts who want to update or modify their “small block” 144, 170, 200, or 250 or the “big block” 240 / 300.

These great engines have been overlooked for their performance potential and what little knowledge there is has been sparse and hard to find.

We’ve amassed quite a bit of experience with Ford six engines from Australia and Argentina as well. Our forum is the web’s only place for antique Ford Inline sixes from Flathead thru 215/223.

And we haven’t forgotten all those Orphan Inlines from Rambler, Packard, Hudson, Pontiac, and all the rest. Check out the Orphan Inline Section.

Keep an eye on these pages as we detail our projects and look at links to other six-cylinder Classic Mustangs, Falcons, Fairlanes, Ford Trucks, and other Ford cars.
