I am hoping this is head and valve related, if not I will re ring the engine.
I will be selling off the head, however it was interesting that the valves were sunken below the surface.
There is a crack in the top of the head from one welch plug to the other, but hopefully a person who needs and wants a 27 head can have this repaired.
The top of the block is in pretty good condition, with not too much corrosion around the water holes.
You may see that I have about 5 mm of oil sitting on top of each piston.
The water pump is a bonus, in very good condition.
The water inlet from the head is surplus to fitting a 28 head, and will be sold.
As will the single port exhaust manifold
I will also be selling off the 27 Carb and inlet manifold, that are in running condition, as I will be fitting the bigger 28 inlet manifold and 28 carby.
I find the internals of a 27 dizzy a bit agricultural compared to the 365B fitted to 28's, but it works, cant be changed, so it will be kept.
The next step will be to fit a 28 head, which hopefully will raise the compression across cylinders 1,3 and 4 to match 2.
If nothing else this will be a great training exercise for me, and a bonus if I get a good spare engine as a result.
Will keep you informed.
