560 power loss. What to do about it?

Posted by Farmall Daddy on November 13, 2003 at 07:35:46 from (165.139.17.193):

I just reecently dynoed my 560 gas. It has the original piston set in it that was sent from the factory. It only had 55 horsepower from what the dyno said when the motor was cold. As the motor warmed up, the power went down to 50. Should I overhaul it with the bigger piston set, or keep it original. I use it around the farm, and occasionally for pulling in the 10,000lb class at tractor pulls. Never had a problem with power loss in the 10,000 first gear, torque back. Pulled good, but my compression rings are bad. What size of oversize piston will fit without boring the motor to a 301 cubic inch? Thanks for the response!!
