The engine has a strange box shape between the cylinders. The Unobtainium exhaust instructions require you to remove this. I am not sure which exhaust to use at the moment but the box section doesnt seem to do anything and its not on the original engine. anyway its gone now and the resulting hole is covered with a bit of plastic card The engine has gone through white primer, white gloss, some parts titanium and some a sort of bronze gold. If this 1968 car follows the path of modern Honda Engines the bronze parts would be magnesium but i dont know going 60 years back. The original engine shows a bar across the rear which is the throttle bar which links left and right cylinders (top of pic) Also look at all that detail between the cam covers, none of which is on the model but in fairness it wouldn't be seen under the exhaust which exit out the top there as well. oddly this is missing on the kit, they give you the levers each end and the backets to hold them but they are not connected I found a bit of 1.5mm alloy tube that fits through the brackets, it has a 0.9mm bore . I cut the pins that locate in the brackets off and drilled them out and fitted some 0.9mm steel pins and a 33mm long piece of tube This looks better but i am wondering thy Tamiya didnt do this, i have looked ahead and i cant see it will foul anything later but this might come back to bite me.
