Thanks!

The alternator on the LT1 is clocked different from yours. If you don't mind pulling the case apart, you can simply re-clock it to fit the LT1.
I strongly recommend re-sealing the LT1 intake manifold prior to installation. The ends are sealed only with RTV, and it dries out after a while and makes some good oil leaks. GM has very specific instructions on re-sealing it, down to the bead-size on the new RTV.
Also I recommend replacing both the oil-level sensor, and the knock sensors, because both have a tendency to rupture internally causing oil leaks. Another problem area is the distributor. It's behind the crank pulley and water pump housing so its a PITA to replace it in the car (don't lose the intermediate shaft when you pull the water pump!). MSD makes a nice upgrade, but its $$.
Here's one I did a mild build on for a Qatari customer.
