The 1972 AAR "Mystery Eagle" on display 

The Lyon Air Museum of Santa Ana California recently hosted the “Vintage Motor Racing exhibit” with a special tribute to Dan Gurney. This was a fitting memorial as Gurney’s All American Racers has been based in Santa Ana since 1970. One of the two AAR Eagle race cars on display was a recreation of the historic 1972 “Mystery Eagle.” shown as it appeared at the 1972 ‘California 500.’

Veteran racer Jerry Grant began the month of May 1972 without a ride for the Indianapolis 500-mile race but campaigned for the seat in the second Eagle for Dan Gurney’s All-American Racers (AAR) team. Grant was an ideal candidate for the highly sought-after ride in second AAR Eagle, but there was a problem: Gurney had a fast machine but no sponsorship.

Gurney and Grant had a long relationship which dated back to 1965, when Grant first co-drove with Gurney in a Lotus 19 in the Daytona 2000-kilometer race. Grant had driven for All-American Racers in 1966 in the ill-fated Gurney-Weslake Ford engine powered Lola T70 sports car in the USRRC and SCCA Can-Am series.

On Thursday, May 18, 1972 Jerry Grant was formally announced as the driver of the second AAR 1972 Eagle painted purple and white and dubbed “the Mystery Eagle.” The car appeared to outsiders to be unsponsored, as aside from contingency decals, there was only the logo of CV Enterprises on the rear wing and the company logo “You Name it” emblazoned across the nose of the car and on the rear wing end plates.  

CV Enterprises was a company operated by the mysterious Christopher A. Vallo Junior, a self-described millionaire from the Chicago suburb of Highland Indiana who also owned property and a restaurant in Minnesota.  Vallo, a Korean War veteran of Greek descent, had been convicted in 1965 of passing counterfeit currency and was sentenced to three years of probation.

In late 1970, the 265-pound Vallo approached stock car builder and racer Ray Nichels and his son Terry with a check for $1 million for the Nichels’ to build Vallo a team of winning Pontiac stock cars.  In November 1971 Nichels filed an $8 million lawsuit against Vallo that alleged non-payment per their contract terms.  

According to fellow historian and writer William LaDow, the contact for the 1972 Indianapolis ‘500’ CV Enterprises sponsorship came through Bobby Unser, who introduced Vallo to Gurney during the month of May when Gurney was desperately searching for sponsorship for a second Indianapolis entry. In hindsight, given the nationwide publicity given to Nichels’ lawsuit, one wonders why (or if) Gurney was not wary of Chris Vallo, or perhaps he was that desperate for sponsorship.  

The terms of the agreement between the pair was never revealed, but Grant got the ride on May 18 over Unser’s objections, as Unser reportedly wanted a sprint car driver as his teammate according to Gordon Kirby. On Friday May 19, 1972, Grant took his first laps in the #48 “Mystery Eagle” and after just 20 or so laps of practice, posted a best lap of 186.881 MPH.

The following day, after the remaining “first day” qualifiers failed to knock Unser from the pole position, Grant qualified for the 1972 Indianapolis 500, his sixth Indianapolis start, in the 15th position. Grant’s four-lap average speed of 189.294 MPH with the last lap run at 191.164 MPH, was the fourth fastest run overall, and the fastest qualifier of the third day non-pole position eligible cars.

 

In a post-qualifying interview with the Associated Press, Grant commented on such a fast run after so few practice laps. “Sure, I’m excited. But it’s easy to explain. I have the world’s best former driver as a car owner and the world’s best current driver as a teammate.” According to Gordon Kirby, however, there was tension behind the scenes, as Unser who had done all the testing and development work, resented Grant’s immediate success. 

The 1972 Indianapolis 500 featured a new rule that required that, a car take on fuel during at least four mandatory pit stops during the 500-mile race. The rule further stated that “approved procedures under this supplementary regulation will be covered in bulletin form.”  The total amount of fuel allowed for each car to complete the 500 miles was 325 gallons, the same as 1971 but with one additional stop required.

Each car started the race with 75 gallons of methanol fuel on board, and the pit tank limited to 250 gallons. While a total of 325 gallons seems like a lot of fuel today with contemporary electronic engine controls, it was going to be close for many teams in 1972 to average better than 1-1/2 miles to the gallon with their mechanical fuel injected turbocharged engines. 

At the start of the 1972 Indianapolis ‘500’ on Saturday May 27, pole-sitter Bobby Unser took the lead at the drop of the green flag and led the first 30 laps until his car retired on lap 31 with ignition problems. Gary Bettenhausen, in Roger Penske’s McLaren then took control of the race.  

Grant battled with Bettenhausen and took the race lead of lap 162 when Gary pitted and then held it for three laps until he pitted and Bettenhausen resumed the lead. On lap 175, Grant retook the lead and held on while Bettenhausen’s car retired on lap 182 with ignition problems. Bettenhausen’s teammate Mark Donohue inherited second place but was nearly a lap in arrears.   

While in the lead, Grant’s Eagle began to vibrate and “push” or understeer entering the turns with what Grant thought was a bad right front tire, so with just thirteen laps to go, Grant was forced to pit a fifth time. Without working team radio communications since early in the race, with only hand signals from the driver, Gurney and the crew surmised that Grant’s Eagle was running out of fuel. With the “Mystery Eagle’s” 250-gallon pit side fuel tank empty, the crew stopped Grant in teammate Unser’s stall.  

In a chaotic situation, the crew connected the fuel hoses, and then Gurney realized the problem was not fuel and ordered the crew to disconnect the hoses. The AAR crew changed the right front tire before they realized the problem was with the left front tire. 

By the time the disastrous pit stop was over, Grant’s car had been stationary for 38 seconds and Mark Donohue in the Sunoco DX- sponsored McLaren had swept past into the lead. Over the final 12 laps, Grant could not close the gap and crossed the finish line nearly a lap behind Donohue.

To finish second after he led the ‘500’ with thirteen laps to go must have been a crushing disappointment to Grant and the AAR team, but the worst was yet to come.

George Bignotti, crew chief for Vel’s Parnelli Jones Racing, owner of third-place finisher Al Unser’s ‘Viceroy Special’ filed a post-race protest which claimed that Grant’s car should have been “automatically disqualified “after it took fuel from Unser’s fueling tank. Bignotti’s protest was reviewed by the stewards overnight, and meanwhile, the AAR team studied videotape as they suspected that the USAC scoring was wrong and that Grant had actually won the 1972 Indianapolis ‘500.’

When the official race results were posted at 8 AM on Sunday morning May 28 1972 , Jerry Grant and the “Mystery Eagle” were placed twelfth in the finishing order. Chief Steward Harlan Fengler, Referee Don Cummins, and Steward Walt Myers had upheld Bignotti’s protest and that Grant was not credited any laps after the pit violation, just as if the car had retired at that point.  

After a hearing the USAC Appeal Board announced their decision on Wednesday afternoon June 7 1972.  While the panel agreed with Dan Gurney’s claim that the lap 188 refueling of Grant’s car was a mistake, as the car did not need fuel to complete the race, Chief Judge Charlie Brockman said that Gurney’s  “line of testimony is not relevant. The stewards cannot be responsible for the mistake of a contestant. The panel respects Mr. Gurney’s forthright honesty as he admitted that he would have taken the same action and chanced whatever penalty had he positively identified the need for more fuel.”  

The USAC Appeal Panel determined that a violation of the rules had occurred and cited the 1972 500-mile race Approved Supplementary Regulation #23 which stated that the maximum fuel supply other than that carried in the car was 250 gallons.  

On the heels of the stunning loss of more than $71,000 of Indianapolis ‘500’ prize money, Gurney and Grant found that the mysterious Chris Vallo had disappeared. Like Ray Nichels and David Pearson the pair wound being owed a lot of money which they would never collect.  Until his death Jerry Grant would show visitors to his home a copy of 1972 check for $10,000 from CV Enterprises stamped twice by the bank “NSF” (Insufficient Funds). 

In March 1976, the law finally caught with Chris Vallo, then 45 years old, as he was convicted on several federal counts: failing to file income tax returns, making false statements to obtain bank loans and firearms and possession of firearms as a convicted felon.  Vallo who had earlier filed for bankruptcy to escape several civil judgments was sentenced to five years in federal prison. Upon his release, Vallo remained out of the public eye and passed away in 2000.

Grant’s promising 1972 USAC season came to a halt for lack of sponsorship with the purple and white #48 AAR Eagle grounded for three months. In mid-August, Gurney’s primary sponsor Oscar L “Ozzie” Olson of the Olsonite Corporation, manufacturer of molded one-piece plastic toilet seats, announced that he had purchased the “Mystery Eagle.” 

Olson announced that Jerry Grant would run the final three USAC races on the 1972 schedule, starting with the third leg of the USAC ”Triple Crown” the ‘California 500’ at the 2-1/2 mile “Indianapolis of the West,” Ontario Motor Speedway.

Practice at Ontario California began on August 22 1972 and both the Eagles of Grant and teammate Bobby Unser soon posted practice lap speeds of over 200 miles per hour (MPH). Experts calculated that the turbocharged Offenhauser engines in the AAR Eagles had to produce nearly 1,100 horsepower to accomplish the 200 MPH feat.

That huge amount of horsepower from 159 cubic inches of engine displacement came at a price as the high level of boost pressure put a tremendous strain of the engine’s internal components.  Unser experienced two engine failures in practice and then in pre-qualifying practice on the morning of August 26, Unser’s car suffered another engine failure, which opened the door for Grant.

Jerry Grant’s first lap around the Ontario Motor Speedway in the purple and white #48 “Olsonite Eagle” lap was completed in 44.7 seconds, or 201.414 MPH. Jerry Grant was the first man to officially turn a lap in an Indianapolis-type championship race car at over 200 MPH. Grant’s lap broke Peter Revson’s day-old Ontario track record of 194.470 MPH and set a new world’s closed course speed record and took the two-year old "world’s closed course speed record" away from NASCAR stock car racer Bobby Issac.

Grant’s last three laps of his 10-mile time trial run were progressively slower, but he would start the ‘California 500’ from the pole position with a four-lap average of 199.600 MPH. In a post-qualifying interview, Grant explained “I didn’t want to push it, so I backed off a little after that first lap. The track is slick, and I didn’t want to make a stupid mistake.”

Grant seemed a bit underwhelmed by his accomplishment. “Going 200 MPH to say you’ve gone 200 MPH is not the object. I want to get a good starting position in the race and any of the three in the front will be fine with me.”    

Meanwhile, the AAR crew replaced the engine in Unser’s car in time for him to make his time trial run later on Saturday, but rain showers in the area kept Unser off the track and therefore he was ineligible to make a run for the pole position. The next day, Sunday August 27, Unser’s Eagle blazed to a new track and world’s record with a lap of 201.965 MPH and a four-lap average of 201.374 MPH but because his run came a day too late, Unser started the 1972 ‘California 500’ from the twenty-third starting position.

If there was any question of the level of animosity between Grant and Unser, it was answered by Grant’s quote printed by the Associated Press after Unser’s record-setting run. “Isn’t it ironic?” said Grant, “the B team is sitting on the pole and the A team is back in 23rd?”  Unser later told Preston Lerner "that record should have been mine.  Letting Jerry get the record irks me like hell because I did all the development work on the car.”

In pre-race publicity, AJ Foyt predicted race laps would be in the 175-180 MPH range with engine turbocharger boost levels reduced and the cars carrying full fuel loads. In final practice on September 1, Grant ran a lap with full tanks at 190.779 MPH, and Unser practiced at 192.028 MPH. In an article published the day before the race the Long Beach Press-Telegram ranked Grant as a 10-1 favorite to win the race to be held on September 3 1972.  

Jerry Grant’s “Mystery Eagle” failed to complete the first parade lap of the third annual $700,000 “California 500” before a rod bolt in the Offenhauser engine broke. The magical flight of the "Mystery Eagle" at Ontario was over.


In an interview days later with Ohio sportswriter Rick Yocum, Grant revealed “I never felt more confident about a race in my life than I did about Ontario. Usually we change the engine after qualifying, but mine was running good, and you hate to fool with something that’s working so well. We changed pistons, valves and bearings, but not the bolts.” 

 Grant ran the two final 1972 USAC races - the penultimate event at Trenton New Jersey where the engine failed after 53 laps, then in the season finale at Phoenix were he was flagged as the eighth place finisher. While the 1972 season certainly did not have the results Grant and Gurney hoped for, Grant will forever be remembered as the first man to post an official lap in an IndyCar at over 200 MPH. 

Fellow historian Jacques Dresang noted that the original "Mystery Eagle" was sold to Bruce Crower in 1973 who still owns the chassis. The car shown at the Lyon Air Museum is a tribute built up with a NOS (New Old Stock) tub.
