they don't want to tell you.
further - there is probably better now anyway

They looked into it, none of the people who were involved then work any more and apparently none of the designs/specs were passed on from old to new people (lost as they say)
They had no clue about press pins either and said I would need to work out the interference specs for them

The rods they made back then were a press fit. Mahle sill make the pistons for those engines and its still a press fit as it was 30 years ago.
I'd go for Argo any day since argo been making rods for multi 1000 hp racing boats for like forever. I can tell you water craft have a much harder time than a vehicle, know that one from experience lol.
I'm the director of VSH (Vlad's Spec Holden), because HSV were doing it ass about.
