Default Re: 21A rods set up on a 4" Merc crank
I has the fortune to know the guys at Verdi rods & oilpumps.
They has a grinder that create this surface, se picture.
AMC made that machine.
I make dry sump oil pump parts to them right now.
I think the extra 0.001" sounds a good idea as get all this spun nice and free.
What I'm think of if I ever need get the copper 'look' surface of the bearings, so has any ideas what it is ?
