Showtime – Don Erwin’s ’65 Fastback Mustang

Page 1

It’s not uncommon to see the wheelie bars set high on Don Erwin’s “One Trick Pony” 1965 Mustang Fastback. After all, he didn’t earn the nickname “Showtime” for rolling with the crowd.

A veteran car guy and drag racer, Erwin has owned this car since 1984 and has become quite well known at the tracks he runs, if not for his wheelstands and prowess behind the wheel (of any of his 3 cars), then surely because of the incredible paint scheme on this Mustang – half of it is red and white, and the other half is white and red. Wait a minute, isn’t that the same color combo? Ah, but it is absolutely not. In probably what is one of the more original looks we’ve seen, Erwin opted to reverse the dominant color from one side of the car to the other, and here’s the rub – even though you know that one side of

The unique and very cool color scheme for the Mustang was not only the brainchild of owner Don Erwin, but he did the work, too! It’s amazing how our brains work….when you look at each side of the car separately it looks like a different car.

The latest iteration of the Fastback’s power is a stout 9.5 deck 351W based small block with Yate heads that is stroked to 393 inches. A monster F3 ProCharger centrifugal supercharger sits low up front, in fact the placement necessitated minor surgery to the original front crossmember.

the car is the opposite, try watching a run from one side and then the other. Your brain’s first response is to think it’s a different car! Then reality kicks in a split second later and the cool factor really sets in.

Self-employed with his own auto repair business, it didn’t take Don long to start modifying the car the way he wanted it. Going through various combinations over the years, he would eventually be hitting the drag strip with a stick-shifted wheel-standing naturally aspirated 351W based combination in 2015. It wasn’t as though Erwin was new to the strip, though, as he has been drag racing since 1973.

In fact, he is 10-time track Champion at Ozark International Raceway Park, held the track record for ET and MPH off and on for 10 years in the True Ten 5 class and was inducted into the Southwest Drag Racing Hall of Fame in 2016. So you might say that Don has his game on when it comes to racing.

Wanting “more” for the Fastback, Erwin would step up to a monstrous 632 big block, but that still wouldn’t quench his thirst for power. More recently, with the continuing itch to go quicker and faster, he went

It’s pretty much all racecar inside the Fastback, with very little original equipment left aside from the dash pad. Red cage bars snake throughout the interior and the original floor and custom tin work is covered in bright red carpet. A digital display is inset in the dash face and electronics are neatly laid out near the passenger kick panel with a full 2 row switch array mounted within easy reach above the driver.

all-in to capitalize on the Mustang’s appealing looks with a hardcore big power small block boosted combination that would take the Fastback to a whole new level.

Chassis wise, the car has been backhalved while keeping the front frame relatively intact, and if you look closely you can make out the original front frame sections amid the sea of chassis bars. Along with that, the car retained its body tub, firewall, doorjambs and even the stock floor to the rear of the doors, so it really is a true 1965 Mustang, which is becoming a scarce sight these days.

the car.

So what’s the story on the paint? As it turns out not only did Don come up with the unique paint design for the car, but he also did the paint work himself. Have a closer look; it really is remarkable how the Mustang looks like a different car from one side to the other.

Thanks to the chassis and suspension work, the Mustang sits low and mean. The custom rear chassis is complimented by a fabricated and heavily fortified “TYDO” Ford 9-inch with 3.89 gears that is suspended by a coilover 4-link setup with antiroll bar. Up front, tubular control arms with struts and rack and pinion steering were used, and for the most recent build, in order

Struts with tubular a-arms and rack & pinion steering were used up front with the factory frame sections and a custom 4-link/coilover setup suspends the TYDO fabricated 9-inch rearend in the rear of the Mustang.

to make room for the massive ProCharger, a portion of the original front crossmember was sacrificed.

Exact details on the new power combination are slim – Don doesn’t want to give away too much – but we can tell you that it is a small block 9.5-inch deck Ford 351 Windsor based mill stroked to 393 cubic inches. A forged rotating assembly and top secret custom grind roller cam designed for boost were packed into the aftermarket block. A set of the mighty Yates heads with all the goodies were studded in place and a matching Edelbrock/Glidden 2868 intake capped by a Mark Sullens blow-through E85 carb and Extreme Velocity Pro Series hat top things off. An F3 ProCharger with Supercharger Store overdrive takes care of adding boost to the package and a tricked out Powerglide with Neal Chance converter send power rearward.

Inside the car, there is very little original Mustang equipment left. The floor, custom trans tunnel and rear tin work are carpeted in bright red, which is the theme throughout. The cage is painted to match as is the original dash pad which is fitted with a digital display screen to transfer vital signs to the driver. A billet pistol grip Hurst shifter controls gear changes and Don resides in a color coordinated race seat.

As of this writing, the new combination has seen testing, however no full power or competitive passes have been made, but we’re sure when the Mustang does make a full hit that it will be in the usual Showtime Don Erwin fashion…pedal down, wheels up and hang on!
