what does your early abody look like?

Running 415 small block, 10.2 compression ,904 pushbutton, 4:11 gear on 28" x 12.5 with Edelbrock heads. Running with mufflers the best time ever was 11.42 116mph. With open headers 11.35 119mph. I don't have a roll cage so I got only two trys with the headers open before the track told me to slow it down.
