For those looking for a Dark Horse with HP, my local dealer has a brand new one for sale. Premium with comfort seats, 6 speed mt, color is DMG. Located in western NY. I believe they are selling at MSRP...
The S and the R versions started back with the S197 Boss 302's. There were slight differences between the two versions, but both were race cars. I would assume that will be the case with the Dark Horse also.
The GT350 and GT350R were both street cars. The Dark Horse R will be strictly a race car only. The race version of the GT350 was called the FP350S and had a 5.2 liter engine but it didn't use a flat plane crank (like the GT350 and GTG350R) due the unreliable nature of the flat plane crank engine.
So my DH with HP that I ordered on 3/27/23 is now listed as previewing with the dealer. They said Ford might just schedule to build it. He also stated Ford told them they will start building HP cars shortly. Now I see the wheels for my order are not available now, but Ford must think they will...
