p76
The P8 model. Extensive work had already taken place on this power unit in order to produce the required power output for the larger P8 model and it was logica not to allow this work to go to waste. Leyland Australia P76 gets raised (approx 17mm higher) and stroked Rover 3.5 block+crank with same pistons but longer rods and bigger main bearing shells in 1973 - new capacity is 4.4 litres. Everything from Rover 3.5 except crank and rods can be used on the P76 4.4. P76 4.4 crank can be used on the 3.5 as a stroker crank.By comparison, the stroked Rover engines (4.2 and 4.6) kept the same rods, block height and bore as the 3.9 but reduced the piston crown height to accomodate the extra stroke on the crankshaft. The Rover approach is superior because you get the capacity increase without having to change the block height, rod length, inlet manifold width and external dimensions as well as the crankshaft.
