Will,

     I gather from the tone of this message that you are thinking about 
     non-Land rover engines but I must say I am VERY happy with the Rover 
     4.2 installation in my '87 Range Rover.  It now has plenty of power 
     and accelerates like a normal car rather than the slug it was.  And my 
     gas mileage has actually improved because I don't have to work the 
     engine so hard.  The engine was taken out of a wrecked LWB and rebuilt 
     by Rimmer Engineering.  It cost me $4,000 plus core for the long block 
     and didn't include installation.  While that is significantly more 
     than you might have to pay for a Chevy or Ford small block V8 or V6, I 
     think it's more than made up for by the fact that installation was a 
     simple R&R.  It uses all the original intake and ignition systems, 
     starter, etc.  I'm even using the original EFI computer which is 
     working fine so far, although I do plan to put in a later model 
     computer with the 4.2 chip whenever I can get it working (my friendly 
     at-work electronic technician hosed something when he de-soldered the 
     3.9 chip and installed a plug-in socket for the 4.2 chip).  Using a 
     Land Rover engine and all the original induction and emissions 
     equipment is also a BIG advantage when it comes to emissions testing 
     and inspection.  I passed first time with plenty of margin.
