Hello Aspirant,
According to the category and rank you have mentioned in the question you cannot get IIIT Delhi with any of the branches as per previous year's cut-offs because last year the closing rank for IIIT Delhi through JAC Counseling was 329 for CSB branch for a General candidate of state other than Delhi. You can check out previous year's cut-offs from the link given below :-

But yes I would suggest you to sit for some state counselling because in some of the state government colleges you can get admission on such ranks.
Note that the cut-offs are bound to change every year depending upon various factors.
So you can use JEE-Main College Predictor to predict your chances of admission in different engineering colleges of India :-
