67 Dart 270...Project Old School

I have been fighting with my Hurst Promatic II and based off the "internet" stories, most people give up. It took a week of constant tinkering, but I think I have the shifter lined out. I am thinking the tight tunnel confines from the physically larger A500 has the shifter cable turning tighter and adding more drag on the cable. My solution was upping the spring pressure in the shifter mechanism to insure I got complete motion from the ratchet action.

Since my shifter hasn't been right it is hard to provide conclusive data on the power loss from the A500. The only data I have is from an 1/8mi track (Bonne Terre) that I have only been to two times. The time I went with the 904 it was cooler and the car ran a best of 8.29. Running in the July heat with a shifter that wasn't right I ran a best of 8.45.

I also need to get the car reweighed in it's current configuration. I am hearing the A500 weighs 70 lbs more, but I think that includes the heavy lockup converter, which I did not use. I added the trans weight, Small 8" sub box, acoustical mat, door panels and door latch hardware. I removed the AC/Heater box and have the console out of the car. I am thinking from a weight stand point that the Dart is about he same as before.
