Narrow A Body 360 Oil Pan

their are (2) 360 pass car pans that I have seen. both "center" sump pans. on one the sump starts 2" rearward from a plumb line straight down from the front lip and the other 4". iirc one of the two was a 294 stamped in the bottom, I cant remember the other #. iirc the 2 incher would hit the Kmember as the sump is too far forward. EDIT I think there was a 392. not sure which one was the 2 or 4 incher. aftermarket ones I have seen a ~4" back
