I have a 1971 Chevy Cheyenne C10 that I've had for 18 years now. I pulled the motor several years back and had the block reworked - this is the original motor and first rebuild on it. The bore was taken .20 over and the crank was .10 on rods/mains.
My question is - will I have to replace the pistons or just get .20 over rings?? It has been many years since I built a motor and couldn't remember...
Thank you..

 

you will need 20 over pistons as well as rings.
