Kevko oil pans?

I've never seen an aftermarket pan that looks remotely oem. I took two oem 360 pans and cut the very bottom out of the first pan, and cut the sump out of the other, and added the sump to the first pan. IIRC, it added about 1-1/2 to 2in (?) to the sump depth and a couple qts to the 360 pan capacity. That part was fairly easy, extending the pickup was the hard part.
If you put on a deep pan, it is going to hang lower, and be exposed to impact. You might want to add a hemI skid plate to the k-member, and/or add heavier t-bars to avoid bottoming out.
