I used the stock Mopar 1970/71 440 6 pack and street hemi pan in my old pump gas 1971 Duster with the motor moved back a little to clear the stock K frame, 6 quarts and not very deep up That car ran 10.00 with one 9.993 ET at 134.+ MPH in the 1/4 mile and never had a oiling issue as long as I kept the oil level above the add mark up
Lots of runs and lots of street miles boogie

Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)
