Big Block Chevy BBC Champ CP208 oil pan. 8 inch sump. Screw in dipstick, windage tray, trap door crank scraper with wall lip. Has a tapered sump but oil filter and starter was easy to access. This was in my 64. It fit but I had to space the mounts a little. I would assume this is for a 68 and up. Nice pan for a 496.
