I'm running that setup(SM465 into 2.73) now in my '84 K10. It cruises real nice on the highway, but because my 305 bent 8 is short on low end torque, I'm the slowest thing in the world off the line. I've got a 292 waiting to go in this truck when the 305 finally dies(194K and counting). I suspect the 292 with it's great low end torque will love this gearing.
