a milder cam profile might be required depending on emission. Something like a comp XE268 MIGHT pass.. but the 274 would probably not.
3.10 gear is pretty strange.. most were 3.08..
I would go with a 268 probably.

you didnt say what your doin about heads so that will play a role aswell..
for a daily drivin 400 id say get a cam that would be "hot" for a 350...
ive seen a few dynos of different 400s using a cam with less the .500 lift makin 450+ horse...
if your worried about emissions then go with smogger headers, hi-flow cat and a 4 inch exhaust
