Rebuilding engine- Need advice (and to vent)

Wow, That is a very VERY nice Roadrunner, I would be under the car removing the dust
shield and T.converter bolts, and strap the trans up to stay in place, remove the starter, radiator, fuel lines and carb and pull that numbers matching engine and get it on a stand I believe.. That is a superior car and well worth a new carb or have it rebuilt by a pro, Thats what my planes would be on that great 72 RR. I could do the engine but the carb would have to be dun by some one ells... Nizzze RR.
