ok, yes rod and caps stay together. im just researching type r stuff. recently purchases a type r short block in a disassembled state, "previous owner spun a rod bearing, and i noticed all the rods have the "R" and all the caps are marked p72. however the rod and cap have been etched 1-4 with the respecting connecting rod to keep them together. just needed to solve this puzzle. so basically im screwed or have any engine builders out there seen this before?
type r "R" connecting rod with p72 caps. thanks for all your help everybody!
