We first saw this car at the Mid-America Shelby meet in Tulsa, Oklahoma, and were stopped dead in our tracks. It was low, wore fat rubber, and under the hood was a menacing looking Cleveland power plant. It was so impressive my 16-year-old nephew Cody, who was along for the show, took several photos of it, declaring, "that is exactly what I want in a Mustang." We went back several times before we had to leave Tulsa for our home base in central Florida. Sadly, we never found the owner by his vehicle. At first I didn't realize the impact the Silver SportsRoof had made on my nephew, but he couldn't stop talking about it when we got back to Florida. After drifting all over the Mustang map as to what body style he wanted, he finally settled on the '69 SportsRoof style and the weed slammer profile. And we have David McMillan of Dallas, Texas, to thank for converting another soul to the blue oval family.
Personally, I couldn't shake the SportsRoof either. It was a home run for us here at Mustang & Fords. Big Cleveland mill and all, it was perfect, but I thought lost to the show gods for another season. Then came the Mustang 40th. At the show we were steppin' and fetchin' just to get what we wanted done. it was hot and dusty, and we were nearly full up on sweet restomods. As we trolled the rows looking for a '69 or '70 to fill the last spot on our dance card, we found it-and this time David was around to share.
First, there were the big meats: 275/35VR18s up front and 315/30VR18-inch drag radials out back. These stickies are mounted to 18x8 and 18x9 Billet Magnums from Wheel Vintiques. according to David, there was judicious massaging to get it all to fit. The interior is Mach 1 and aside from the Billet Specialties wheel, a six-point cage, FloFit seats covered to look like Mach 1 buckets, and an Autometer Monster 5-inch tach, the interior is decidedly stock. Outside, the Silver Dupont Chroma base paint applied by Ray Mitchell was still as slick as ever.
Under the hood, the 377-cube 351 Cleveland had been packing a set of vintage SVO B351 heads and vintage SVO Cleveland intake when we saw it in Tulsa. Now that combo feeds the huff of the seven-psi Procharger to headers and eventually a set of Flowmaster mufflers. The carb is a specially reworked 750-cfm Holley tweaked by CSU of Colton, California. Igniting the mixed-up fuel coming from the electronic fuel pump is an MSD Billet distributor and 6AL box. Once the fire is going and the clutch is dumped, power is fed through a T5 five-speed and pitched back to a 9-inch diff packing 3.50 gears and a traction-lok.
We were pretty upset when we missed the car at Tulsa, but glad we caught up with David at the 40th so we could see just how huffy he'd gotten over us missing his car. With 497 Procharger horses, we can bet it's now pretty huffy, indeed.
