What's the Pros and Cons of running a 5.7 versus a 6.0 rod for the 10.5 to 1, 360 IMCA spec motor?

shorter rod is supposed to help torque. longer rod will hold higher rpm hp longer. the longer rod will have a lighter pistons than a comparable 5.7 so that helps with load on the rods and acceleration. i run the longer rods and use a smaller cam to get the torque back.
