I think it would be sack religious to install non American made connecting rods in a SD build when you already have a useable set of SD rods. JMO
I would concentrate on the cylinder heads and camshaft. That will make the difference between jaw dropping performance or average power. I posted a build in the 70-73 tech section under the Super Duty Forum thread on my 74 SD that ran 12.7 weighing over 4300 lbs. using 3:08 gears.
