need 340 help

great thanks for yalls help, i only drive the car once a month or so around town, i just really want to be able to hop in it, enjoy it, and make some good power, the motor was in a 65 barracuda with a 3000 stall and 3.91 gear and went 12.80's but im sure that car is lighter than mine. i was thinking around a 3500 stall and a 3.91 gear, but then what size tire should i run? im clueless when it comes to that.. and if i went with a bigger cam what should i run? and whats the better intake the single plane M1 or the Victor jr? THANKS AGAIN!
