I have a 92 3.0 v6 5-speed and im thinking about swapping it out with a 5.0 v8. Is there any motors and trans that should fit right in with very littls modifications?

 

No, not really

Ford 302/5.0l V8 fits in engine bay so is the best bet, it one if the smaller sized V8 engines, 19" wide, most are 25-30" wide
If you run a carb and distributor then you don't need the computer or wiring
Still need exhaust system, radiator

You can use M5OD-R2 manual trans or an AOD automatic and then custom driveshaft
Also need to relocate transmission mount


If 3.0l is failing or failed, just replace it, and sell that Ranger
Buy a V8 Ranger already converted, way cheaper for most unless they have done a few engine swaps in the past

 

The 5.0L out of an explorer has a shorter FEAD. Back in the day we had to do that to make the 5.0L fit (I was the water pump designer on that project)
