i dont remember at 60mph but at 80mph my engine is around 2600rpm with 3.23's. i know a LT1 has a 1800 stall. the LS1 should be pretty close to same.

you can check the vehicle speed with any gear ratio or tranny Right here...

you can also get the rear tires off the ground and spin one wheel 1 full rotation while counting how many time the driveshaft turns. that will also determine the rear end ratio
