Demon 340 vs Camaro 396 (400)

My buddy has a '69 chevelle 396 4.56 gears, I have a '71 duster 340 3.73 ratio.
We run 1/8 mile,we run very close, last year I beat heads up.
He put new roller cam,intake, carb. He is a little faster than me now. It won't take much to catch up to him. We have fun competition between us. 20220813_154200.jpg 5408.jpeg
