I have had to surface grind SB rods to fit the crank
on one of my engines... I should have gone back to
the crank company to have them do their job right..
he messed up and turned the crank to chevy diameter
but didnt do the width right.. on my last engine I did
the same thing but went back to him and he did the width..
on the SB I ground .013 off the inside of each rod
to fit with clearance
