410's are not acceptable for 35 or 38's. you need to run 456 for 35's. With 456 on 35's you will get good gas mileage and your torque and hp will stay the same. you can still run 456 with 38's but your top speed on highway will be slower, mpg will be kinda bad and you will lose some acceleration. i would suggest 35's with 456. First of since you have a chevy your front suspension is an ifs, so 35's will be less harsh on your ball joints, tie rod ends and pitman arm. 38's will wear and tear your truck. they def. arent worth the extra inches.
