You need headers for the Chevelle with a smallblock, nothing special.
The motor mount bosses are there for your standard mounts BUT if you keep the AC it uses one of the positions and would require you to move the passenger side mount back on the crossmember.
Far as a fuel pump system, you need a bypass system that can supply 45psi.
Far as HP I would sell the LT4s and get a set of ported LT1 heads from www.advancedinduction.com BIG power gains there.
