Internal engine components, which will obviously not be visible once it's all built, include pistons, rods, a built-up crankshaft, valves (!), valve springs (!!) made of white metal, rockers, camshafts and the gear drive for the cams.
Lots of drilling needed too, bringing my nifty little drill press into use. Pistons and rods are now assembled with wrist pins made of 0.8 mm brass rod.
For those interested, the bore is 6.4 mm, corresponding to the 3.3 litre motor in the 1965 Le Mans winner, but the pistons at 6 mm diameter correspond to the 3 litre 250 motor. So while it might turn over, I would expect some serious piston slap and oil consumption at higher RPM.
Some additional time was required to assemble the rods to the built-up crank along with 5 of the 7 main bearings. Sadly these bearings are cast as a piece and you can't just drop the crank into the block.
Next will be to prep and paint the engine block components, because I suspect the crank needs to go into first one side, then the other, with the rest of the block assembled around it. Stay tuned...
