Enjoying all the great info. I have a 79 280zx going through a 5.3 ls/4l80e swap right now. Just getting started. Has a Ls4 intake I snagged complete out of a parts yard, with adapter plate for 5.3 throttle body. Later on I'll look into a ls1 or ls6 intake. Eventually will be a 6 speed T56 or CD009. Of course I have same issues of engine placement and supporting parts being worked out.
