What Moses said. but I'll add:
4) Don't underestimate the cost.
5) Don't think one source will have every answer to each question that comes up.

I don't know of anyone who is installing 3.6's into an early car as a matter of regular business. TRE would be able to do the job as would other performeance P-car wrenchs. But if you are looking for someone who has done repeated conversions I never heard of any. At this point it would be a custom job.

I did mine myself as my first engine drop and found it quite simple. There is lots of information out there. Just read everthing, twice, and get your ducks in a row before beginning.

I obtained everything I needed from the following sources, not in any particular order:
Harald
IG, Inc.
Patrick Motor Sports
Pelican parts
B&B
Fabspeed
And then were the many board members who contributed their time, tools, and tech support.

Good luck.
