I once dropped a Seagull Century Plus into my old Rover 105S.
It improved consumption considerably though at the expense of performance to windward, uphill - or any bleedinwhere actually.
The biggest difficulty, especially in traffic, was helming the old girl from the rear seat . . .
As far as I see it the only real problem is to make sure you've allways got enough flexible water hose on a reel (which will probaby have to go on a trailer). If you dip the end of the hose in a river at your departure point and lash it down then you should always have a good flow of coolant water. Obviously you need a length of hose greater than your longest intended journey, and a reel capable of unwinding at 70 mph. about 24000 reels of B&Q value 20m garden hose should be good for 300 miles. /forums/images/icons/crazy.gif

Translation: OK - but don't expect us to ride it afterwards!!!
Translation #2: Don't ever carry your loved ones in it again and don't mention it to your insurance company.
I can imagine some problems with torque steer or possibly propwalk if keeping the propeller as propulsion.
Also visibility may be hampered although head through the sun roof sounds good.
I think the radiator will need to be upgraded too, possibly to soemthing resembling the size of a barn door. Again a visibility issue here.
What about weight distribution ? Assuming front mounted engine, your gonna need a big weight at the back to counter it ? How about fitting an engine at the back too ?
Failing that you'll need at least 5 people the size of BIGNICK to be with you at all times to ensure good handling
