Re: The Pontiac OHC Six
I'd rather use 40 yr old steel rods than most of the stuff you can buy today, but I'm weird.
Fully counterweighted crank: it has a counterweight between each pair of rod/main journals, the other type does not. Reduces the loading on the crank because the stress from each rod is pretty much all contained between the adjacent mains. Most (older?) V8 cranks have no counterweights between the center two rod journals, for example.
