Great looking rig! I have an 87 with a g54bt in it on 33 bfg km2 with some toyota shackle lift, roof rack, and soon to be sr rear locker and front arb.
My next swap will be a diesel though. You can pull about 28mpg out of a 4d56, and the reliability is excellent.
Mine isn't as pretty as yours, but I take mine ito anything and everything lol.I wouldnt bother with a 4g63t swap, you will want the extra low end powerband of a g54bt over a 4g63t imo, Especially when going with larger tires. I suppose if you changed the transfer case gearing it would be find, or double transfer cased it.
I'm assuming you would run some toyota trans if you went 4g63t.
Lately I have been thinking about runnign a divorced transfercase like a atlas, in with a starion transmission to beef up my current drivetrain. The stock trans are pretty damn weak.
