I kind of feel like you're getting beat up, but that's not really the intent. We have the best intentions for you. I did a lot of research on the same situation, looking at Ford Racing 306 v 347. Yes, they're more expensive because they use all factory parts, but they basically said the 303 cam shafts they're using to generate their high numbers make those numbers come on at higher RPMS. Crate motors are deigned for cars, not a heavy Bronco. Even Ford Racing will send their crate motor to a shop in Texas (whose name escapes me at the moment) to swap out the cams before they send the motor to you if you are putting it in a truck. My take is you'll be fine with either motor and the 4:56/33s/NV3500. The gearing will work fine for having power come on at 2500 rpm. You can always downshift when passing on the freeway. You should be OK on most trails and minor crawling if you use your transfer case to get the taller ratio. You have a 71 so a "T" D20 which has a taller gear than the "J" D20. You just won't get a lot of grunt at slow RPMs and high gear, like passing without downshifting at 60 MPH. The reason to ask Blueprint about the cam was simply to see if THEY could put a different cam in (for free) when they built it. How they work is they build engines all day long an have many in stock. You call, they send you what they have. They're not really set up to build a custom version, but it didn't hurt to ask what it might take. I think I'd push it and tell them you'd wait for a few weeks if they could put the cam in you want. Probably not going to work. As with the Mexican blocks, probably not going to hunt one down for you, but it doesn't hurt to ask.
As for the extra money on the torque, my belief, not knowing the exact details on their build, is everything else being equal, a stroker always produces more torque at a lower RPM than a comparable unstroked version. So you'll get more torque, and it will probably come on maybe a couple hundred RPM lower. Ask them to send you a Dyno sheet from each version and look. My feeling is more and lower RPM torque is worth some extra cash, but 370 is a lot of torque to begin with. You won't regret either motor.
