Looks like there is still some decent support for the Windsor family after all.

Probably not as many options as someone that will put one together practically to your specs and even include TBI on it, but still pretty good.
I wonder about the E303 cammed 340hp model, vs the B303 cammed 345hp model though. These might be better for a light car than a heavier Bronco, because the E303 cam is widely acknowledged around these forums and others to be a pretty crappy cam for a Bronco in a standard motor.
Perhaps it's not so bad in a higher compression, aluminum head equipped engine, but plenty of precedent to keep the horsepower lower, or the cam milder, for our trucks.
If you go with Ford factory EFI you will need a ECM tune to help the engine run better with that E303 cam. Got a friend with a standard Mustang computer in his Bronco and it frankly has way too much lope and lacks the throttle response and grunt that we know should be there otherwise.
Lots of similar reports from users of that cam here too.
But at least the Ford Performance group still sells a few options if you decide to go that route.
Good luck.
