Background

edit

At the 1973 Indianapolis 500, several violent crashes marred on-track activities. Art Pollard was killed in qualifications. Salt Walther was seriously burned in a start crash. At the time of the Pocono 500, Swede Savage remained in critical condition from a lap 57 crash. In the aftermath of Indianapolis, USAC moved quickly to improve safety before Pocono. [2]

At Indianapolis, cars were permitted to hold 75 gallons of fuel and an additional 275 gallons in a pit road tank. For Pocono, fuel capacity was decreased to 40 gallons and fuel cells were only permitted on the left side of the car. Furthermore, teams were allowed 300 gallons in the tank on pit road. Rear wings were reduced from 64 to 55 inches. It was hoped the smaller wings would reduce speeds.[3]

1972 Indianapolis 500 champion, Mark Donohue's entry in the Pocono 500 was initially disallowed by USAC because he had an SCCA racing license. On June 18, Donohue received approval to race because the Pocono 500 had FIA sanctioning and was approved as a "foreign graded driver."[4]

Practice and Time Trials

edit

During Wednesday's opening practice session, Mike Mosley set the fastest speed at 185.6 mph.[5] Mosley was making his Pocono debut after he was injured in crashes at Indianapolis in both 1971 and 1972.

On Thursday, Bobby Unser had the fastest speed at 186.900 mph. Al Unser was second fastest at 186.339 mph, Gordon Johncock third at 186.038 mph.

Rain on Friday morning shortened practice time. When the sun came out in the afternoon, Lloyd Ruby posted the fastest speed at 189.122 mph. Peter Revson was second fastest at 188.670 mph.

Despite the efforts of USAC to slow the cars with smaller wings, there was little effect on speeds. "What they did wasn't a drop in the bucket," Johnny Rutherford said. "The reduction in wing size was supposed to have cut speeds a bit. But look at these guys go out there. You can hardly tell the difference from Indianapolis."[6]

Time Trials

edit

Qualifying runs were a four-lap, ten-mile average speed. On Saturday, June 23, Peter Revson won the pole with a 190.468 mph average. Revson's best single lap was 191.367 mph. Both four-lap average and single lap speeds were track records. Revson was joined on the front row by Al Unser and Mario Andretti.[7]

Jerry Karl, driving a car prepared by Smokey Yunick, crashed on his qualifying run.[8] Engine problems kept Gordon Johncock and Mark Donohue from making qualifying runs on day one. 21 cars posted speeds.

Day two of qualifying was led by Gordon Johncock with an average of 187.578 mph. Mark Donohue was second at 185.510 mph. Johncock and Donohue started 22nd and 23rd respectively. The day's track activity was shortened by rain before all cars could make a qualifying attempt.[9]

With only 27 cars qualified and six spots still needing to be filled, a final qualifying session was scheduled for Wednesday.[10]

Dick Simon was the fastest car in Wednesday's session at 180.054 mph. Jerry Karl's car was repaired from his Saturday crash and he qualified on Wednesday.[11]

In a repeat of the 1972 race, massive rains fell at Pocono leading up to the race. On Thursday night, a nearby city recorded five inches of rain in a half hour. Continued rain on Friday added an additional two inches of precipitation. The majority of Pocono's infield was still dirt from the recent construction which turned to red mud. Water stood knee-high in some garage areas and infield tunnels were flooded.[12]

Race

edit

USAC's new rules meant fuel consumption would play a major role in the race. With only 40 gallon fuel cells on the car and cars getting 1.8 miles per gallon fuel economy, it was predicted teams would need to refuel 12 or 13 times.[13]

Chasing the 1973 Formula One title, Peter Revson was required to run USAC's Triple Crown of 500 mile races as part of his contract with McLaren.[14] Revson was forced to miss the French Grand Prix to run the Pocono 500.

1957 Indianapolis 500 winner Sam Hanks drove the pace car for the race, a 1973 AMC Javelin AMX specially prepared by Raybestos to be given to the race winner after the checkered flag.[15]

When the green flag was waved, polesitter Peter Revson was passed by Mario Andretti who started on the outside of the front row in third. Entering turn one, Johnny Rutherford hit the wall and brought out the first caution of the day. Rutherford was able to continue and finished fifth.

Three laps after the race restarted, Al Unser hit the wall in turn one with the rear of the car and punctured a hole in the boiler plate steel wall. Unser was hospitalized with a mild concussion, sprained neck, and minor lacerations of both legs. The race was stopped for 45 minutes to repair the wall.[16][17]

Gary Bettenhausen crashed in turn three on lap 38.[18] Johnny Rutherford brought out another caution on lap 55 when he spun in turn two. The polesitter, Peter Revson, fell out of the race after 75 laps with engine failure.[19] Lee Kunzman hit the wall in turn one on lap 83.

While leading on lap 137, Indianapolis 500 champion, Gordon Johncock, blew a tire on the frontstretch and avoided contact with the wall. Johncock was unable to continue after leading 46 laps. Debris from Johncock's car cut both rear tires on A.J. Foyt's car.[20]

Roger McCluskey held a one-second lead over A. J. Foyt as the cars approached the final pit stop. Jim McElreath stalled on lap 171 to bring out the final caution. McCluskey pitted on lap 172. Although the car's fuel cell held 40 gallons, McCluskey's chief mechanic Don Koda calculated they only needed 30 gallons to make it to the finish of the race returned the car to the track.[21] Foyt pitted one lap later and took a similar amount of fuel, but stalled the engine leaving the pits. Shortly after the restart, McCluskey had a four-second lead over Foyt. Foyt's car developed a vibration and McCluskey extended his lead to ten seconds.[22]

Foyt made a green flag pitstop for fuel with seven laps remaining, while McCluskey tried to stretch his fuel to the finish. McCluskey had a 42-second lead over Foyt as he entered the final five laps.[23]

As the race began the final lap, it became apparent that McCluskey's crew failed to put in enough fuel on the final pit stop. Entering turn one on lap 200, McCluskey ran out of fuel. Foyt passed the slowing car and won his first 500-mile race since the 1967 Indianapolis 500. He became the first man to win four 500-mile Indy car races, the Pocono race joining his then-three wins at Indianapolis. It was the first time a 500-mile Indy car race was decided by a last lap pass. Foyt won $94,808 and was the only car on the lead lap. McCluskey failed to complete the final lap, but finished second, which earned him $48,933.[24]

Only eight cars were running at the finish. The race saw 29 lead changes, a Pocono 500 record that stood until 2015.

One day after the Pocono 500, Swede Savage succumbed to his injuries suffered at Indianapolis.[25]
