5.13 and 37?
I feel the 5.13 combo is a little too much gear for 37" tires. I think you might run out of rpm before you hit the middle of the pit, and with the engine screaming, you will just not have the wheel speed, or vehicle speed that you will need to do well.
Shifting in the pit will be tough, and you will lose the wheel speed you already have, and I am pretty sure, that you wont be grabbing a higher gear with a 360. Now you will have the option of using high range, and maybe second gear, or a higher gear, but I still think you will run out of gear, and puppy power before you reach the end, even if the mud just isn't that bad.
The tires won't stop spinning, but may not spin fast enough with 5.13's to get you in the money. I could be way wrong here, will look foward to see what others say, but I am thinking 4.56's or 88's might work a bit better here.
