Were you the guy on the other forum with the Falcon? To be honest, I don't think you'll like that cam if you're gonna run a 3.50 gear.
I had a customer with a Cobra replica that I built a 482 for. It had a similar camshaft and the car was a 5-speed with a 3.50 rear gear. Even at 2400 lbs weight, he wasn't happy with the powerband as it was pretty soggy down low and then just came on hard at the top. We ended up changing to another solid cam that was about 20 degrees @ .050" smaller and it made the car much more enjoyable for him.
At the very least, I would consider a custom camshaft. In applications like this, the engine would benefit from more exhaust duration (6-8°) and to be honest, I would drop the overall duration down and tighten the lobe centers up. If you're for sure going with a 3.50 gear, that would help the engine be more "helpful" at lower rpms while still sounding mean.
To answer your question though, with the spring pressure you'll need and the lift that the cam has, I'd go with something like a T&D street. There are other options available of course, but I consider T&D to be one of the best out there.
