It's a low 13's-high 12's combo if you can get it to hook. My car is similar with stock heads, less cam, and runs 102 in the 1/4.
The carb will be the choke point up top. Not near enough IMO.
naw, no way 12's. the cams too small. compression too low. Need at least 9.7:1 and a good 284/484 (something around 240 @.050). mill the heads to up the compression

Lots of opinions here .... even if he goes with the 150 shot of nitrous ?

Tuned right that will get into the 12.90. Don't need a lot of motor to go that fast if it hooks and runs right. It might run high 11's on juice.
So I guess a 340 with 3.91's, short tires and a 214*/224* at .050 cam can't run low 13's at over 101? I clearly did something wrong. 
The listed engine is capable of about 380-400hp, maybe a smidge more, if the carb is changed to a 750 or better. That's enough HP to push a 3200-3300# car to a 13.00 or slightly better.
Don't need huge cams with lots of duration to get a car to run low 13's. He won't get near the low 12's without juice, and would need to up the cam/compression/carb/gear to get there on motor.
