I need help

O.k. guys, some co-worker's and I are thinking about doing the big swap. Out with the slant 6 and in with the 360 and 904 tranny. I have 90% of the parts. Now, how hard of a project is this going to be? I have the bigger torsion bars, schumacher motor mounts, rebuilt engine, trans will be rebuilt soon, have a guy lined up to shorten the drive shaft, and a 8 1/4 rear. I will be ordering a mallory unilite and coil, alum. radiator etc, etc, etc. How nasty of a job is this going to be? What should I expect? Any advise and help wanted.
