Thanks Martin, I really appreciate that comment. This engine looks nice in the pics but great in person. real nice satin shine. Did some more. Added the engine mounts. Some blocks had 10 mounts, 5 per side. Some had three per side. I suspect that these are 'newer' more recent blocks or the 'oldest' style....don't really know. there was some weakness to the block originally, and a new beefier bearing mount type design was used. The Miss America VII of 1930 had the 5 per side engine mounts. I went with the 3 per side, because you really can't see them.
The whole engine is held together by 8 main 2-56 bolts. Two for the cam covers, two for the heads, and one for the carb ( a single bolt into a brazed 1/4 brass solid rod. rod acts like a clamp and holds the intake together), 2 for the cam flats, and one small bolt for the carb filter.
The solid cam covers have flats milled to their bottom sides which fit milled head surface. The cams are round on the ends, which fit respective cam covers or flats. The flats each have a bolt holding them to the heads. this creates a clamp like effect holding the heads together tightly. The cam covers do not fall out because they are 'locked' on to the head.
waiting on some tiny false bolts to do the block covers.... have not decided how to build the exhaust. Found some 1/12 spark plugs on the net (sold locally in Ohio USA!!) so bought 16 of them. Did not feel like machining them!
Tight fit in the engine bay .... and looks scale appropriate!
