I will be installing new axles with 373 gears this comming spring. I will also be putting on 35" tires. T-case is the NP-203. Tranny is a TH350. Now my question is: should I consitter a 700R4 ???? Or stay with the TH350. I was thinking beefing up the TH350 and possibley going to 4:56 gears, but I'm now thinking a beefed up 700R4 might be the way to go. What do y'all think ???? Plan on using my Blazer as a DD and for trails.
