Hej Tim,

Engine is supposed to be a 1979 907 standard engine with the standard liners( they are iron- magnetic) / pistons, Liners is honed but I do not know weather the rings have been changed.
Crankshaft and rods are coming from a Bedford of some kind?
I meassured compression ratio to 9,5:1. Cams are something similar to 107/104 ( Reprofiled cams)
I measured my compression Cold by screwing the manometer into the plug hole, opening the throttle fully and crank the engine using the starter, until the reading stops increasing.

I think I will change the oil to a 20/50 mineral before i take out the engine.
