The engine and transmission are painted and assembled. Other than a little touch up, throttle and clutch linkage they are done. I think it's a pretty cool looking engine.
The block is an aluminum silver, then I added some satin black to the same silver for the transmission color and all of the bolts on the block. I gave the tranny a black wash, but left the engine bare, the sheen from the silver gives all the detail needed. I had to fight the urge to do all the accessories in red for contrast, instead I did them all in Alclad. the only color is the red of the magneto and the turquoise of the wires.
If you notice, I did find a way to mount an alternator. It looks like the drive for the mag comes around from the side of the block, I added a housing that would hold two gears, one from the mag and one on the alternator. It might not be realistic , but it makes sense to me that it would work.
