Offenhauser 5487

I have a Offy 4bbl intake from my dads 65 273 and am wondering if it would run ok on my 360. The 360 is a 2bbl now and I want a 4bbl but I know I have heard that I have to modify the 65 and earlier intake to fit the 66up engine. Thanks for any input. If someone is close I may trade it for a newer intake.


Sorry I read the # wrong its a 5489 and they are just over 300 new a Summit.
