I know that I would most likely have to re-power sometime in the next couple of years, and I am simply trying to gather some information ahead of time.
Currently I have a 1995 Mercruiser 5.7 TBI/EFI with a Bravo III. The engine has a MEFI-1 computer and a Delco EST/HEI distributor.
If I was going to re-power, I would like to purchase the newer style (1997 and up) Vortec long block, due to the increased power and [hopefully] fuel economy.
I know that right off the bat I will need a new intake manifold to go along with it, but I am curious as to what else I will need to make the swap? I was told that I would have to send my computer (MEFI-1) to have it re-programmed to with with the new engine + I need to buy, or make, a custom harness, but this is where things get foggy.
