Highway RPM with the 200R4. Gotta love it!

For those of you who didn't follow my build post, I put a GM 200R4 tranny in my Dart Sport. I have a Dana 60 with 4.10 gears. With my old 904 I was at 3200 rpm at 55 mph and 4000 rpm at 70. I just got my new dash installed and the speedometer wired and calibrated. It seemed like a perfect time to show how good the rpm is now. I see my oil pressure is maxed out. I tapped the #10 wire from the harness that was supposed to be oil pressure sender. It was the wrong color, but I went with position. Wrong choice, it must not have been the OPS wire. I'm going to run a brand new wire.

70 mph and running 2600 rpm
