Realistic estimate Please

How long domyou think an engine swap will take in my 66 cuda. Please take the following information into consideration.

-Car is currently /6-904
-Going to 360 - 727
-have schumacher mounts
-Motor is fully assembled already
-I have an engine hoist and am planning to insert from the top
-I have never done this before, but I am somewhat mechanically inclined. I did swap out the cam intake carb etc on the motor going in. have done break work oil changes, Strters, alternator changes Etc
-car is already set up with an msd ignition, so I think i should be able to plug the new distributer into the old plug.


Am I crazy to think I can do this myself?

How many people would I need to Help me, none of my friends are really car guys.

My mechanic said he should be able to do it for about $600?
