Get the book "How to swap a GM LS engine into almost anything". Its a great source of info. I'm swapping a 2002 Silverado motor into my 57 Burb. I had an interference problem with the low mounted AC and the stock exhaust manifolds wont work because they hit the frame. The actual bolt in and fit was the easy part. Oh yeah I'm running a TCI MII front. As far as the standard trans without getting into the bolt patterns, the computer can be programmed to use without the factory trans. I'm using the factory 4L60E. Other things you will have to figure is fuel delivery(58psi). Harness and computer work, exhaust, steering, which oil pan to use, etc...
There are two other guys on here one is done and the other is like me... in progress. Maybe they will chime in.
