what carb ?

Im trying to decide which carb to go with on my 340. My goals are for a mid 12 second street car with good throttle response and torque while keeping it pretty much stock looking.
The motor is
.030" over 340,
11:1 compression.
Cam will be a Hughes Solid 242/248 @.050" .543/.563" on a 106lsa
ported iron heads flow 260I / 180E
gasket matched LD340 intake
TTI 1-5/8" to 1-3/4" headers

904 with a 277 first gear
391s with a 26" tire.
