its a good motor though
its the only one i know where you have to fill it to max mark on the dip stick.
getting the dipstick tube in the right depth was never a strong point at Chrysler Australia
and you still have a good half mile to go before the cranks dips into it
crank scarper and baffled sump is a popular upgrade

Yeah OK folks. Everyones engine does that. But usually the factory limiti it to 45-55psi unless it is a High Perf engine where they fit a stronger spring in the pump.

Just to update this, I switched from 20/50 to 10/40 and saw no real drop in pressure. I started chopping coils off the bypass spring until I just had some preload on the valve when I screwed the plug in. 3 coils off and I now have 40 psi hot at idle and a swift increase to a maximum of 80 when you bring the revs up. Still waiting for the Milodon adjustable kit to come, when I get that installed I hope to be able to dial it in to around 20 at idle and 65 max, hey there might even be some horsepower in it....
