8 3/4 rear engine dragster gear ratio

iirc, been 40yrs, the econo class was much like a S/S engine, stock block, b&s, heads, comp, with any cam and intake. The "C" class was limited to any 750 cfm carb. The car went 9 teens with a 302 & low 8.90's with the 350. I see no reason you can't eclipse those numbers with modern technology.
