No word yet on what the current bid is, so we'll have to wait and see just how much someone's willing to shell out for this over-the-top build.Condition and DetailsThe Chili Red paint job came courtesy of a previous owner, with plenty of wet-sanding and buffing to get it shining. Like most old Mustangs, it had its share of rust gremlins – front subframe rails, shock towers, and radiator support all needed attention. The seller replaced everything from the firewall forward, plus floor pans and inner fenders. There are still some paint chips and stress cracks, all shown up close in the listing photos.1968 Ford Mustang Fastback 363Bring a TrailerThe chassis has been substantially reworked.

Forget just swapping in a bigger engine – this Fastback gets the full treatment: 363ci Dart stroker, ProCharger, six-speed manual, custom rear end, modern suspension, beefy brakes, chassis bracing, and wide wheels. It's built for way more performance than Ford ever dreamed of in 1968.1968 Ford Mustang Fastback 363Bring a TrailerThe powertrain is particularly unusual for a first-generation Mustang. The Dart block uses billet four-bolt main caps, a Scat forged crankshaft, forged H-beam connecting rods, Wiseco forged pistons, AFR 205 heads, and a custom-ground camshaft. The ProCharger D-1X then pushes the combination to a dyno-tested 879.21 horsepower at the rear wheels.Final ThoughtsThis 1968 Fastback isn't playing in the same league as your average restored Mustang. Its value comes down to build quality, that wild 879-horsepower number, all the chassis upgrades, and how clean the finished product is. Classic.com's $132,583 CMB and $152,985 average for custom '67-'68 Mustangs are a good starting point, but every car is its own animal.You get build records, a clean Iowa title, and paperwork for all the mods. The 6,200 miles on the clock? That's just what the current owner has put on since the rebuild. If you're thinking about bidding, check the rust repairs, paint quality, all the hardware backing up that monster engine, and make sure the paperwork matches the story.ild.Disclaimer: This post is for informational purposes only.
