anyone wanna guess what my 1/8 mile will be

My '75 Duster with a 360 with J heads with 1.88 intakes, 282 484 purple cam, Performer RPM dual-plane, 600 DP MSD ignition, 1 5/8 Flo-Techs into 2 1/2 Flowmasters and H-pipe, 3.55 gears with spool, 904 with low gear set and TCI $700 converter, battery in trunk and weighing 3200 with me and a full tank of fuel runs 8.00 at 85 mph in cold weather and 8.20 in July at 1000' sea level in NC. I can disconnect the secondaries and it will slow down 1/2 second in the 1/8. I would guess that your dart would run 8.50 @ 80 mph. The converter alone can make a 1/2 second difference in ET's.
