I had a 258 balanced at the customers request. Used the stock crank and rod assy. Crank came back with a 3/8 hole about 1.4" deep on one counterweight. Engine is now good for 8000 RPm for 240 bucks

The original crank had three 1/2" dia. holes added that varied as to location to a depth of about a quarter inch on one and 1/8" on the other two.
The rods have material removed at various locations on the big and small end.
This was done at a cost of 225 bucks.
