I use the 6 quart mark now (knowing that I filled it with 8) until I can get the dipstick calibrated.
I put in the remaining 1.5 qts, for a total of 8 qts added, plus a filter change. Filter was not pre-loaded with oil. Started the motor and ran it briefly, came back the next morning, and the dipstick reads 5.5 qts. So that's my new 8 quart baseline reading.
The dipsticks front vs. rear have the same initial P/N, but different letters at the end. I will continue to monitor and investigate.
If anyone has access to a TSIO-360 parts catalog, please post the proper dipstick P/N for the TSIO-360CB engines. Thanks.
