Nice laundry list of mods, you definitely have some $$ in it to turn the #.
Roll cage like another post said.
With Jack Cotton tuning you have one of the best helping you!!
I personally would make sure you get the WOT Wide Band A/F ratio lock in the Fast, good insurance at minimum.
You still have some pounds to drop, if interested you can PM me for my laundry list of weight saving tips. I still have the stock heads, block and crash beams and am 412lbs down with about 50lbs left to drop this year.
