Detroit GM - Overlander's Data Collection

Please note the files DD500, 501, 503, 504 & 505 have Swishy's stamp on them.
Overlander may have saved them on his data collection with the rest of it.

Do recall Swishy posting these tables some time back in answer to Detroit queries.
Trust that is ok with all parties. Can be deleted if not. Paul.

With reference to the discussion on the oil pressure, particularly idle pressure on the Isuzu and Cummins engines it is interesting to see those GM figures note a fairly high running pressure of 49-70 psi but for idle they say "nominal" which to me seems to say so long as there is a flicker on the needle all is well. Sort of goes along with the Cummins 5 psi idle figure.

I would think your pretty right Lang

To my untrained brain as long as it's got a little pressure at idle ot should be fine

But at working rev range good pressure is needed as there's a lot of load on the bearings then
