I have a below par engineering gpa (2.64), a decent masters gpa (3.6) and a high gre(326) along with some finance course certifications and 6 years of work ex. in the construction industry. What are my chances to end up in a good university for MBA? Any universities that I should specifically target with that profile if I am planning on making a pivot to finance post MBA? Comments.

Good university is a vague term. Moreover, your goal is not quite clear. Please take a look on the below post to get an idea on the b-schools as per GMAT score -
