And with the .5 coming from stroke, the 3.5 rod 'should' be longer, and therefore weaker-->Correct? Haven't checked 350z forums, but I'd be interested to see how many rods the big horse boosted guys are throwing?? But I agree, they dont make them like they used too. Peace_

The 3.5s tend to ingest the throttle body butterfly set screws or the 2ndary intake runner butterfly screws- this blows em up in no time. I also seen 2 6th gens at the dealer with the block cracked right under the intake manifold.
