I was checking for bent or twisted rods by putting two rods over the same wrist pin and checking to see if the big ends made contact all the way around. I fliped the top rod over so the caps were opposite one another and observed that the distance between the wrist pin ends were closer together,about 1/8", the other way a little over 1/4". All four rods were the same. I wanted to put the rods in with the caps to the carb side so the strong part of the rod took the power stroke instead of the bolt but it appears that shouldn't be done or the rod will not be centered between the piston wrist pin bosses. I installed them per the manual. I have read here in other posts that they can be turned. I didn't want scored pistons so I stuck with the case manual. Any other views on this? I'm working on two other engines, one for a puller with M&W pistons.
