Hello, I have a 1988 Merc Grand Marquee, with the 5.0 Liter EFI.
I love this big boat as a sleeper but the Big ?'s are
I have not found much information on Motor/ Tranny swaps.
I found 1 post that shows a Turbo set up on the stock motor
But the post never gets into the Fuel / Air Ratio on control.

I am trying to find out if this frame is good to be a swap project.
Or If the frame is a odd ball and will be motor picky.
Due to width etc...
