Packard's 60° flathead V12 of 1916, in production till 1923. It has a 3 bearing crankshaft with 6 throws, 2 rods per throw. The camshaft was also 3 bearings, with 24 lobes to open the valves. The oversquare engine produced 85 horsepower from 424 cu in. About 3600 were built.
Adjusting the valves - looks like a cover plate at the bottom of the V will let you get right at them, with the manifolds removed, right? And few inches to work with.The single carb is 'pressure fed' somehow,and has some sort of linkage for the optional clutch control.I'd like to ask the man who owns one.
