"Some guy in Calif", most likely "Armando's
Oil Pan" a copy of the Aviad road race pan. As it's full length, with
oil filter would be 9 qts.
Drain, re-fill with 8 (more or less), pre-fill
oil filter (slightly less than a qt), run engine (fills oil filter completely), shut down and let stand a little while. Total amount of oil used should be 9. Mark your dip stick accordingly.
For BREAK IN, use 8 and pre-fill the oil filter for another qt (or so). Run the engine 20-30 minutes, shut off and then add just enough to get the 9 in there. Then mark the stick. Now CHANGE THE OIL and FILTER!
