You're not going to burn out the clutch by driving it unless it is not grabbing and slipping while driving. As far as the ratio, the K5 should have a 3.08 I believe. All the K5s I owned had that ratio with the factory 28'' tires. 33'' tires with the 3.08 should drive really nice. A lot of guys shoot for that final drive when installing a 5 speed or an automatic with OD
