I am having to lookin into this too, the track gave me a hard time last time I was there.

For the guys running belly pans the rules state- The belly pan must extend from framerail to framerail and extend forward of the harmonic balancer and reaward to rear engine plate and must incorporate a minimum 2-inch-high lip on all sides. A nonflammable, oil-absorband liner mandatory inside of retention device. See General Regulations 1:8 in NHRA Rulebook.. I have a stock suspension E Body with a 5.7 hemi and I can not see a way to go frame rail to frame rail. In the belly pans pictured I see they just encase the oil pan, has the track given you a hassle for this?
