Near stock 73 Swinger first time at the track
Sounds about right... I took a 67 Dart with junkyard 360 conversion and ran it down the 1/4 mile last summer. It is a stock 360 with a dual plane intake, 750 Holley, Summit headers and duals, shift kit in the 904 with a stock converter. At the time I was still running the 7 1/4 with 2.90 gears. The first pass in the July heat was a lack luster 16.03. Not wanting the ridicule of owning a 16 second car, I made a second pass and improved the launch. The result was a 15.81 at 86 MPH. The sad news is it is still a 15 second car.
