It's all in the converter and suspension setup. I have a PTC 8" converter that flashes to 5000, my car is a bit heavier at 3200#'s, 727 trans, comp engineering drag shocks front and rear, stock leaf springs and a snuber.....its kinda like a bee...it really shouldn't be able to fly, but it does.:D
I'm hoping to switch to a caltrac setup this year to see if I can take another bite out of my 60' times.
