so Ive picked up a 1984 bj 60 as my next rig after years of wheeling lwb samurais. my plans are for 39.5 iroks 4.11s with a nwf blackbox and the stock 3b to start. My question is will the 3b be enough for short trips on the highway and beach cruising until I get the 6.0 ready to swap. or should I be looking for upgrades for the 3b asap
