FrankenDuster I love that Charger! What RPM are you at when going 55 and 60?
We were at the GoodGuys Columbus show a couple weeks ago and I am hooked on Pro-Touring. A nice looking good handling car that you can drive anywhere is awesome. I've always been a drag car guy, so with this Duster I had to figure out the cooling, now I'm trying to sort out the converter slippage, next will be getting rid of these skinny bias-ply front tires that suck on the road with big radials out back.

I think what I need to do is to change converters, or have this one adjusted(might call Dynamic), THEN if the converter doesn't make a huge change I'll go to 3.23 gears/
