Hey J.H. Profitt

I was wondering why the 302 makes more power and torque than a 292. I have a 302 in my 51 GMC 1-ton but I had always heard that the 292 was a better motor (newer & more main bearings & higher RPM). It couldn't just be the extra 10 cubes. I'm just looking for more bragging rights for my 302 so please fill me in.
