Delay box question.

[Steve Polhill]

I recently bought a hard tail dragster for cheap money and it has an old K&R delay box in it. Being a Stock/SS and Comp Guy I have exactly zero experience with delay boxes. I'm completely redoing the wiring, plumbing, etc. and I'm wondering what delay boxes everyone is using. This car is going to be a fun bracket racer only so I really don't need all the bells and whistles.

Any input is appreciated.
