Welcome to Ford Six Performance
The Web's Best Inline Six Site!

This website is for inline enthusiasts looking for ways to update and/or modify the “small block” (144/170/200/250ci) or “big block” (240/300ci) inline six-cylinder engines. These great little motors have been overlooked for their performance potential, and what little knowledge there is, has been sparse and hard to find. Until now.....

Over the years, we’ve amassed quite a bit of experience with the Ford inline six cylinder engines, including those from Australia and Argentina. Our forum is the web’s only place for antique Ford sixes, such as the Flathead sixes and the 215/223ci inline sixes. We also have sections for those Orphan Inlines which were produced by GM, Rambler, Packard, Hudson, Pontiac, Jeep, and so on.

Prior to registering for the forum, please read through the Rules & Regulations, as well as the Registration Tips. Thank you.
