Ok, I found my copies of the programs for the Can-Am race and the Texas 500 that were the first 2 races at the speedway.
The speedway was initially built and owned by American Raceways, Inc. They owned Texas International Speedway, Atlanta International Speedway, Riverside International Speedway, Michigan International Speedway, and Eastern International Speedway. President of the company was Lawrence H. LoPatin.
It says that they built the whole complex in a little over 8 months from the first official announcement on January 28 to November.
The Can-Am was on November 6, 1969 and the Texas 500 was on December 7, 1969. They say you could see 85% of the road course and 100% of the D shaped banked oval from the grandstands.
Prize money/posted awards for the Can-Am race was a total of $61,050. 1st place was $19,000; 2nd was $10,650; 3rd was $7,650. Money was awarded all the way to 20th which was $200 (16th-20th received the same)
Texas 500 prize money/posted awards was $93,150. That includes $8,375 NASCAR championship money. 1st had $15,600;2nd $8,150; 3rd $ 5,675. Money was awarded all the way to 44th which received $700. Time trials had total of $ 1,145. Three days of time trials with Thursday 1st $125; Friday 1st- $100; Saturday 1st-$75.
The pace car for both races was a 1970 Ford Mustang Mach 1 with a 428 CJ engine. Color was a special "Texas Red".
The other races they had scheduled for were in 1970 were the Lone Star 500 on June 21, 1970. Texas Trans Am - Trans Am sedan racing championship on April 26, 1970
Can-Am Round Up on November 8, 1970.
