Hii Deep.
Your OBC rank is bit high
As per the previous year cutoffs you have a good chance of getting NIT Surat for mechanical engineering but you might have to wait for some rounds as cutoffs may high during the initial rounds.
You can also apply for other NITs such as NIT Nagpur, NIT Raipur, NIT Jaipur, NIT Rourkela,etc.

All the best.
