Offenhauser 5489 Intake

Ok I am on a tight budget and putting a 360 in place of the 273. I have this intake from dads 65 273 and would like to put in on my 360 in place of the 2bbl thats on it. I know i will have to modify the bolt holes but will this perform better than the 2bbl being that the ports are 273. If someone lived close with a comparable intake I may trade.
