Watch this 1990 Fox Body Mustang Saleen hit our dyno and see what numbers it puts down with the well-known E303 cam, stock heads, and other mods!

The Saleen Fox Body Mustang has become increasingly popular over the last several years. Not that they weren't popular before, but I think we all know how it goes; low-production specialty cars usually see an uptick in popularity as time goes on. Probably due to the fact that they're harder to find in nice condition.

This higher mileage 1990 Saleen Fox Body Convertible is a solid example of a well-kept, high-mileage survivor. It features some period correct parts such as a Ford Performance E303 camshaft, fenderwell cold air intake, 75mm Pr-M mass air meter, and equal length headers just to name a few (see below for full parts list relative to the dyno). Don't forget the elusive 3-piece Stern wheels wrapped in Michelin tires. Talk about holy grail type stuff!
