Default lose the cat?

hey friends, I use my pickup much like a horse here on the ranch. And as you would expect, tall dry grass rubbing on the cat sure can ruin the day.
before I reconnect the exaust to my re installed 5.9 gasser, I was wondering about gutting the cat before doing so. I wouldn't do this to a fully functional cat, this one has 250k miles on it, and is either partially plugged, or crumbled up inside.

I am wondering if a performance chip from SLR motorsports, (or others) would sense the richer exaust from lack of backpressure, and make the necessary adjustments?

Also, putting a reman distributor in the replacement engine. Are there marks on the block for timing? This is the first dist I have removed from a computer timed engine.
Thanks!
Bob
