I'm building a pure stock 440 sixpack engine.
And I'm using stock 440 sixpack rods with bushing for chevy size piston pin.
I'm about to size the bushings right now and can't find a number for the fitment.
Please any one knows.

Thanks.

My rule of thumb is .001" clearance for every 1.00" of pin diameter.

iagree It is better to have .0009 to much wrist pin clearances than .0001 to little shruggy
