I offer my build thread in the Member Projects forum. It starts out very similar to your questions and finishes with timeslips from the drag strip. The thread is entitled LS/T56/240z Engine Swap Mentor Wanted. My build isn't perfect, but I have walked the approximate road that you are starting. Feel free to PM me with specific questions once you have been through my thread. I will try to connect you with others who have been successful. It takes time to write a build thread, so there is lots of info missing from most of them, mine included. Like all on-line forums, asking open ended questions that have already been discussed will get you yelled at, but we all do it from time to time. But you will want to avoid getting yelled at if you can avoid it. Read my thread then I will direct you to other threads that are as good or better. The search function only works if you know the right questions to ask.
