Need A Little help Please

Ok put on your thinking hats and help me decide on rear gear. I'm running a 410 W2 race head engine that's been set to run in the higher power band. 6800 to 7200 trouble is I'm going thur the lights just shifting into 3/rd gear, with 727 trans with 5000 stall. Shifting to second at about 330 foot wit 1.4/ 1;5 60 ft. Need gear right? Question is 4:88 or 5:13 I can only afford one new setup. 4:56 in the car now. running 7:10 99 mph. 2800 pound car. New gear I'd hope would get me into the mid 6's
I think that is within reason. So any suggestions will go a long way to helping me. thanks guys
