all I can say is WOW, even with my 3.73 gears and nitto 275 out back first gear is worthless. I'm putting 4.30 in tomorrow that going to be fun. I'm getting either Mickey DR or BFG DR for street driving. Thye stall rpm is perfect, the car really takes off hard, even though it is spinning bad but after it hooks it pulls hard. The 9.5" converter verse the 12-13" stock really helped rotating mass I think and allows the car to rev faster.
For any auto guy, this and gears should be the first two mods on their list!
