Uh Trevor, you probably have never driven an FFR with a stroker 351W. My buddies 408 w/450RWHP&480lb/ft of torque has 327's in the rear and any place that it is running in 1st gear, including idle, a stab of the throttle results in tire smoke from the 315/35/17 Yokohama A032R's. The FMS X303 cam is a big cam for the 302, I have it in my 342 and it works very well with the extra 40 CI. I would go with 3.27 gears because the motor will produce more than enough torque at freeway speeds (The above 408 made over 400 rear wheel lb/ft of torque from 2000-6000 rpm)
