If your oil pan did not survive no higher wheelie than that you must have let out, broke, or shifted into high. Hey we all have been there. Well I never lift unless the wall is approaching. But, I have broke something and slammed the car down pretty hard. I keep telling people them ole cheap traction bar snubbers bolted in place of the stock lower control arm bumps is a great insurance policy.

I would try adjusting the car for a longer/lower IC. A 60" wheelie bar works well. Don't be mislead wheelie bars although used for wheelie limiting are best suited for controlling the load on the rear tire. In situations where you can only run a 48" they need to be spring loaded to keep from suddenly unloading the rear tire.

Judging from the car pictured I'm pretty sure you staged with the rear tires to get that 60 ft time. If that is your true 60 ft I would not change a thing other than lifting. Ride that baby to the 330 if you are 60 ft-ing 1.0's.
