With the typical engine swap. No.

 

[zak]

The 3.2 L injectors flow a tad more than the 3.0 which helps compensate for the larger displacement

 

[rubydist]

no, the computer recognizes the slight difference in displacement because the mafs reads more air going into the engine, and the computer knows what to do with that information so all is well. btdt.

What happens if the compression ratio changes? Does the computer need to be updated to accommodate? The CR for both 3.0/3.2 is about 9.8, right?

 

[Off Road SHO]

Ah what? Yes you do. The engines are not easily swapped, there are a lot of differences, the injectors being one of them, the engine wiring harness being another. There are differnces between mounting points, oil pans, front timing covers, alternators etc., etc.

What are you really wanting to do and why?

I detailed the changes needed here (including pictures of the gap when using 3.0 timing covers and a 3.2 oil pump: http://shoforum.com/index.php?threads/89-3-2.126342/

Also, I'm running the original '89 computer with the 3.2. No issues, no lights, no problems with emissions.

A broken timing belt does not bend valves in a V6 SHO.

 

[luigisho]

It's not a quick drop but you can put one in

What he said. If it's a stock 3.0 then the pistons will not come in to contact with the valves if the belt snaps.

unless there is a lot of carbon on the piston tops...
