Pro stock wing questions.

No nothing about them, but it look good!

My buddys 68 dart need that real bad. With his new 383 in it, there was a lot of smoke at the end of the track. Thought engine had expired. The 2nt time down the track, he just about wrecked the car on the top end.
He was literally blowing the slicks loose at the top end!!!!
Three, third member, and his tool box, in the truck, fix the problem.
At near sea level, he had more mph then at our local track of 4400 feet.
Soon after that he got married and it's been sitting for some 20 years now.
