Since I've now put the power unit back in the car a couple of weeks ago, it will be a while before I get to try it out. Below is a picture of the mighty 850 power unit, complete with the new ARP head studs (should have just kept the original ones, but threw them out). Please note the low rise thermostat housing. I printed up a pattern in ABS and had a couple cast in aluminium. Hard to find original these days. Plus also shown is the recovered oil breather hose with the original outer covering pulled over new rubber hose inside.
I never fill my tank extensions to the mark. All I need in the tube is enough to see that there is fluid there. More than that is a waste, in my opinion. Extension tubes at half the height would be more practical.
