Replace Entire Engine as Preventative Maintenance?

If you have the means i would change it and inspect the engine for wear and see if it's renewable. Better that than being stranded.

...how much fun the bar stories will be....."remember that time my engine blew on the back straight and the Mustang behind me spun out on my oil and he flipped into the armco?"

Let her blow up. Fun times. Builds character.

I say yes if you already have a good back up motor. I know of a guy who was racing his spec at cota and blew his motor. Cota gave him a bill in the thousands for cleaning the oil off the track. Last I heard he wasn't going to pay it. Even besides the chance of dumping oil on the track, there's the loss of time and money spent for a racing weekend.
