Motorsport offers some nice cams as well as Comp Cams. How big of lift and what duration are you looking for? I have the E303- 282 dur. .498 lift
some options
F303 288 dur. .512 lift X303 286 dur. .542 lift
The largest one listed for Motorsport is Z303 290 dur. .552 lift

The Comp Cams 236HR- duration @ .050 236/248 lift .579
248HR- duration @ .050 248/258 lift .608
You can find these at Jegs or Summit.

Make sure you get with someone local who really knows their stuff and explain every detail to ensure you match it to your application. The machine shop who did your work should be able to provide guidance. There are many cool tricks (such as having your exhaust valves open a bit sooner to keep your compression down) that these guys know about. Above all, make sure you don't let the compression get too high. You're going to want to be able to run on 91 octane if it is a street car. One of my buddies just detonated a cylinder on 91. He should have been running 95.
Most of the brands should be fine as long as they are from a reputable company.

Try a desktop dyno for matching your application/parts. They are a little warped sometimes in my estimation (show more hp/tq than you will probably get) but provide a quick way to determine how different #'s will affect your performance. Make sure the cam you get has plenty of torque. You're going to need it in a Bronco. You can use the advertised "off road" cams as a starting point but remember that you can always get a custom ground cam to your exact specs for a bit more.
Did the 302 come stock in a 65 Falcon?

As fars a I know it wasn't, the 302 came later.

Your question seems a little odd to me. You say you are starting a 302 build and you are looking for a big cam. The usual approach to building a motor that can use a big cam is to get all the parts together that you are going to use and them match the cam to what you are building. If you don't mind me asking, what kind of parts are you going to use for this build. Knowing what heads,intake, pistons, ect... you plan on using would make cam recommendations a lot easier. Flat tappet hydraulic, roller hydraulic, solid lifter, or roller?

I want to get that program! No problem, sounds like you have it under control.
