Drag car or street car. Bullet's got some nasty lobes (including the old UD NF series 904's that are violently quick....but too aggressive for street longevity.

512 I like a big intake ramp and would tend to use a faster ramp on the intake and a less intense (ex: maybe 4-6 degrees shorter at .200 for the relative same @ .050 ramp) exhaust lobe. I like both of the comp series lobes you call out, but Bullet is pretty much cutting edge right now on their mopar stuff. I'd talk to Tim Goolsby at Bullet and see what he picks for your exact combo and how you're gonna run it. Not much about your performance parameters/expectations here to go by...head flow and CR would help a ton. If the Bs's flow in the ~340 range by .550 I'd run something around 272/276 @.050 on 108 in at ~104-105...it'll fly and will pull hard even with the 3.73's. i'm guessing by the Vic intake it's a standard (or slightly larger) 906 size port....if it were a maxie/super Victor I'd put it in about 2 degrees earlier.
