Hey aspirant, At this percentile, your expected general rank is about 21 thousand which I have calculated by using the formula released by the NTA officially that is:

{100-(your percentile)}*8744.69

With OBC category you have managed to get quite a considerable rank and you can get admission in most of the NITs except some of the really good NITs like MNNIT, Allahabad.

You can check the previous year cut offs of various NITs and IIITs on the link below:

Hope this helps.

Good luck.
