Curtis....thanks. You are absolutely right, I guess I should not of added that 1 qt before measuring the volume myself....I took the info from another source stating that it was a 1 qt o/f and as you said it is more like 1/2 qt. I guess I am probably over filled around 1/2 qt.
FYI I got the specs from an chevy SBC specs off of Gilbert Chevrolet website:
Oil Filter: ACDelco P/N PF1218 same as GM P/N 2516056. This is a long style filter that holds approximately 1 quart of oil.
The PF1218 has been replaced by the PF5.
Do you propose I first correct the level than trim the dipstick tube to get the proper level ?
I found some other posts that mention that a windage tray may be causing some false readings...
