[s-cars] 2.5 l stroker

[Tom Green]

Dave,

Have you considered that those internals from the 2.5 eurovan may be  
a ready made stroker ?  The transverse engine block is useless , but  
the bore
is probably the same making the crank throw the desired length.   
Perhaps unfortunate it is not a longitudinal engine.

  Since you are already sourcing some parts from a eurovan engine,  
Ben, perhaps a check of specifications is in order.  Could be other  
useful parts there.

Tom
