To Resize Connecting Rods or Not?

Kind of off the subject. I've ran stock 340 and 360 rods in a lot of braket cars. New bolts and polished beams. Resized and lengths equalized. Bushed and non bushed. Back in the 80's and 90's aftermarket rods were available but VERY out of my budget. We ran those domed Speedpro pistons that felt like the weighed 2 pounds each. We ran those engines 1000's of passes shifting at 7800 rpm and crossing at a little over 8000 rpm. I never broke a rod. I've never seen one broke that didn't have a spun bearing or something else. I admit that we were only making about 500 hp back then. But the stock rods are pretty tough. I've seen a lot of SBC broken stock rods. But the SBM stock rods are pretty tough. But they are heaver than the SBC.
