Good info! & on a side note there are several 360 pans that I have seen, a 392 & a 876 both of which has a sump ~8" long & the sump starts 4" from a plumb line straight down from the front lip on the 392 and 2" on the 876 & the 876 is needed for a 360 swap into an early A body and they use different pickups, the 392 pickup has a long sweeping bend & the 876 has a near right angle bend. there is a 360 van pan which has 2 indentations in the bottom on either side, not on the sump. #438. EDIT meant to say the 876 pan has the long sweeping curved bend pickup. MORE EDIT its the 392 needed on an early A 360 swap
