I'm not 100% sure on that, can't say one way or another, I don't have one handy to measure, so I don't want to say one way or another. I do know it clears small block and big block as long as there's at least 6 inches before it dips down to the sump. If you see my picture, that's a big block 62 to 65 b body oil pan, my rack sits 1/2 inch below, and almost an inch in front of where my tape is butted up
