Don't know about a source, but people have done this before. See David
Hardcastle's book 'Tuning Rover V8 Engines' for details.
The only problem I could see is that your rod ratio (which seems to have
become a key measurement recently) might not be so good with the smaller
block.
Having said that, its a lot easier to find stuff for the Rover engine (water
pumps, starter motors, inlet manifolds) than the P76, so if you can create
an engine based on this, it'll be less hassle in the long run.
What about an RPI engineering 4.6 short block?

Does anyone know of a source for a Leyland P76 crankshaft? Any
idea of cost? It may be a hair-brained scheme, but I want to use it in a
3.9 liter (241 c.i.) Rover block with whatever combination of pistons and
rods is possible. I do know the main bearings are 2.5" instead of 2.3". I
want to use Buick 300 heads because of bigger valves and larger combustion
chambers (54 cc instead of Rover's normal 36 cc). Also, I have the Buick
300 heads but no Rover heads. I do, however, have several Buick 215 heads
with 37cc combustion chambers. I would like to achieve about 8.5 : 1
compression ratio so I could use ordinary fuel. I'm probably nuts but what
else is new?
TIA
