Nice power on the dyno sheet. I still think that cam is too big in duration for what you're building. No offense meant to your builder, but I think I would call a cam company (comp or any other) and talk to a tech about it. I think for your c/r and intended use, you might be over cammed. Lets see what others say. I would go for something in the 240/246 duration at .050, and I personally would also go with a dual pattern cam, not a single like you have. Too big of a cam will kill your bottom end, and that's what you will feel the most on the street. I would hate to see you dissapointed after all this work. The RPM intake will be great, and a vacuum secondary carb will give you better performance on the street. Use a vacuum advance on the distributor as well. The Holley Street Avenger series carbs are getting very nice reports...a 670 would be nice on your combo.
