67 Coupe
289 v8
4bbl
I've been told my 7 1/4 differential is too small for the my 289 and that I need to upgrade to an 8 or 9''. Very hard to find either of them, at least where I am, but I have found two possibilites and now come to a choice. There is a seller willing to trade a 9'' for $380. There is also an 8'' for $200. Still waiting on ratio info. I know the 9'' is stronger and better for raceing but I don't plan on putting anything larger than the 289 in the car for quite some time though I will be doing other things to improve it's performance. If I do decide to get a bigger engine later though it will probably be even harder to find a 9''.
Can anyone offer some wisdom to aid in my dilemma?
