there are (2) "center sump" pass car 360 pans that I am familiar with (might be others). One is an 876 (stamped on bottom) and a 392. The 876 has an ~8" sump that starts ~2" rearward from a plumb line straight down vertical from the very front pan seal lip and the 392 is ~4" and the sump is also ~8" long. the 876 takes a pickup with a long angled smooth bend in it & the 392 pickup has a sharp almost right angle bend. the 392 will work for sure & not sure if the 876 will & the interference point is from the back of the kmember to the front of the pan sump. Likely you could do carefull measureing with out an eng in the bay & see if the 876 will work (it for sure would if you trimmed the K a bit) but I would rather know for sure & get the appropriate pan for no cutting. EDIT The sumps ain't exactly "centered" but are somewhat in the middle, not all the way rearward like your truck pan or all the way to the front like a van pan.
