[Shotimes] rod bearings

[Bruce Malachuk]

Just outta curiosity, in replacing the rod bearings if one does it as a
"preventative action" do you need to worry about different sized bearing
sets?

I'm a little confused now, whereas before this topic came up I wasn't. I've
been thinking about doing these on my car just cause I like to get on it a
little to much. Plus the previous owner was one to "lug" the car in 5th gear
at really low RPMs.
