What If Build Ideas...for Land Speed Racing

It would have to be Mopar NA powered for me. I’ve been 160mph in the 1/4 and that seemed slow. What rear gear are most of the guys running in the 200mph class.
I am still researching, but it seems like the lowest 8.75 gear is like 2.76 range. I have seen some talking 1.76 Axletech centers!
