debating between 4.10 and 456 i want 430’s but i cant afford a 12bolt right now… so im stickin to my 10 bolt. it really wasnt that bad cruisin on the highway in 6th today… just had to stay above 72ish at about 1700 rpm or it started serging. so 4.10’s shouldnt be too tooo bad. i do drive it on the highway alot and i dont watn to be totally screwed on the trips to s.carolina that i do about 2 times a year.
