what a mess

[Robocop]

I searched this site and found much information on hiding wires but I need to know what wires exactly I can hide.My motor is out awaiting my 331 and man there is a lot of wires in there.Should I wait until my new motor is in before I attempt this in order to make sure all the wires will reach?Do I simply hide the two main bundles on each side of the engine bay?I guess I am asking for what bundles exactly can be tucked away and some good pics would be very helpful.I like the neat look of many of the members motors and I now have much room to work with.I simply cant imagine hiding all these wires.I never knew there were so many until I pulled my motor....thanks in advance for any help
