I haven't been able to look at the journal diameters yet...
But if he was able to use the series II knife edge crank, and get the assembly balanced he would then be using more of the power to propel the car as opposed to moving the engine internals.. Although the series I pistons and Rods are larger and heavier..
Would be interesting to see of that was possible

Hmm...
Just one question from the peanut gallery here.... What about the rear seal? Series II uses a one piece crank seal on the flexplate end. Series I has a two-piece rear seal. The flange end of the crank is completely different in a way that can't be altered by re-machining...maybe...turn it down in a lathe to fit the 2-piece seal of an SI block?
I can envision the finished product bleeding oil like the Exxon Valdez...

Yes it was odd Curt, for the 1990 Tuned Port 3800 they went to the One piece but continued to use the 2 Piece Vin C block.. In 1991 the vin C block was changed over to the One piece( Same block minus a couple of threaded bolt bosses
