Is you AT or MT.
The 3.0 is a pretty dependable and simple engine. Head parts are cheap and very available.
Strong bottom.
Only original valve guides are an issue on these engines.

If you've got alot of bucks and time due a 4.3 conversion.
That engine , trans, t-case ,driveshafts , fuel pump,ECU and wiring system, exhaust system, etc. etc., etc.

a 3.0 out of a Hyumdai sonata, and you'll need your original intake,plenum,T.B., distributor.
If you've lost all those parts there are folks on here that can help you find the parts.
