I thought the Y32SE crank had a slightly longer stroke, though?

Depends if the piston deck height and/or rod length takes this up.

That's not to say there isn't a combination of parts that would work, maybe some skimming of the pistons required, and calculation of the resulting CR?

Slightly longer stroke and wider bore.

Pretty sure something can be found to fit or be made to fit

Food for thought then, thanks gents

There used to be a Vectra ST down Pembrokeshire way running a supercharger on a 3L lump pushing 300bhp, I can't remember what was done but I do remember that he reduced the power due to being advised by his tuner that he was not sure if the bottom end could take it, you may be able to find the build still floating around online somewhere.

Are you sure about 300 hp? often rev up to 6K? maybe better to concentrate more tq

...... and the 54 degree GM V6 is the right package size......

Maybe true, but if my memory serves me well then Renault is the same degree v6.
And I am mentioning this engine only due to the fact that when choosing something reliable no one will think renault.
To be fair it has a very small problem with coilpack, but if its going to be used with custom ecu one can use different coils from different car make.

that engine was considered, but mating it to a RWD gearbox can prove a headache. I went through alot of V6 engines !

 I thought Volvo used it in thier 260  which was RWD
