Oh, my! That's a pretty big cam. The only experience I have with a cam that big was in a 440 cid engine, back in the late '80/early '90s (292 cam in a 440 Roadrunner) It had a 3.55 diff gear, and a Torqueflite 727 with a torque converter from a 6 cylinder car (that was an old trick, even back then) It ran well on the street, because of the extra cubes, but I would think that in a 350 cid engine, you would need a bit of gear and converter to make it work well.
