I have a Ford 65 and it seems like a nice piece. You don't need it now, but it would definitely help. As for where to get it from, look around at the classified ads (here, StangNet trader, Corral) and you can find one for $300 or so. There was a local guy here that sold his for $225! You can find sweet deals on used Cobra intakes. I got mine with the Ford 65 TB for $350. If you want new, I would get it at Summit, but have them price match it to the cheapest you can find in an MM&FF or 5.0 mag. I have seen them new for as little as $369 I think. That'd save you $30!
