Congrats, same model here, put all the standard stuff in your sig - engine,
trans, PS, PB, AC, ext. color, int. color, options, etc. so people will know better how to answer most of your Q's.
Please let us know what you have planned for a budget for engine, etc. so we'll know what direction to point you also. An engine 'rebuild' means different things from $500 refresh to $3K stroker rebuild. How much power are you looking for?
I sent my 289 off to be be stroked to 331, machine work, parts, labor to assemble longblock will be ~$2600 but that will vary by area, shop and what you reuse/replace.
What are your intentions for the car - weekend cruiser, daily driver, any track time, etc.
Welcome to the madness and post a pic if you can.
Jon
