When they are not spending their Friday evenings at AMS, the two can be found operating Cobb's Auto Repair in Griffin, Ga., a business that has been family-owned for 30-years. It is through Cobb's Auto Repair they can fund their drag racing addiction. An addiction that has been in the Cobb family as long as anyone can remember.
"I knew Arnie was going to be into drag racing from a very young age," Arnold Cobb Sr. said. "When you grow up doing mechanic work, racing gets in your blood and it never gets out. I just would have never guessed that we would be racing cars worth this much and putting this much money into it.
"But, you don't have long here on earth and you can't take any of this stuff with you when you leave, so you better enjoy it while you can," The elder Cobb said.
The younger Arnie started drag racing in high school and like then, his father still plays a major role in their drag racing.
"He built the engine and transmission in my current drag car," said Arnie. "He also did all of the welding on the car. He really is the man behind it all. I do the electrical work, tune it and of course, I drive it."
The Cobb's race a 1974 Chevrolet Nova equipped with a big-block Chevrolet engine producing upwards of 1,300 horse power. Fans can see Cobb race his black Nova in the Super Pro division at AMS.
On any given night you will find Arnie, his father, mother, wife, daughter and sister on the AMS infield taking in the tire smoke and race fuel exhaust. Part of what makes racing at AMS so special for Cobb is the recognition he has gotten from the experience.
"Racing at AMS is nice because it is so close to home and it's easy for people to come out and watch the races," Arnie said. "On Monday's, people come by the shop all day and tell me they saw me at AMS on Friday night. The fans there are great."
While Cobb is still searching for his first final-round win, he feels he is getting closer and closer and it is only a matter of time before he will be crowned champion for a night.
"We really have been racing ourselves until we can get the car dialed in," Arnie said. "We are just trying to get a little faster and while you are really never finished working on a race car, we are pretty close. I think we have a great shot at that championship this year."
Regardless of the wins, losses, trophies, or blown engines, drag racing has brought a father and son closer than they already were.
"When I was growing up, Pop and I didn't always see eye-to-eye," Arnie said. "But as he grew older, I grew up and now he is my best friend and my mentor. I plan to do this as long as he can."
Fans can watch the Cobb's race their black Nova during Castrol GTX Friday Night Drags at Atlanta Motor Speedway. More information can be obtained by contacting the Atlanta Motor Speedway ticket office
