for a 3.0? that's a 'decent' price considering that the 6g72 is the most available Mitsu engine around and has the most parts avail.

I'd hope you are getting ALL new head job and valves and seats, etc,etc,etc...blah..blah..blah.. for that $$$$

My rebuild was less then that and was a "performance" 3.0

As for the shop... never heard of them... GOOGLE them and see what comes up
