Too much time around Jasa...

I probably would have just done the swap, kept the carbs, and keep my mouth shut.

You'd need a 2nd gen exhaust to clear the oil cooler though.

anything is legal as long as they don't check. think of it as restrictor plate racing.

So I'm back to being curious, what on a 2nd gen crankshaft is adjustable?

I'm not a parts fiche geek but I was under the impression that nothing much changed in the bottom half of the motor on a gen2 - meh that curiosity satisfied to any rate and I think Trace got his answer in spades....

First Gen you can adjust the crank endplay (actually this is function of the case) second gen cases you do not have this adjustability. Oil cooler, again case difference.

The crank is different as well, even with removing the function of thrust adjustability from the equation. The thrust adjustment is also dependent on the crank, not just the case. You can adjust the thrust with a 1st gen crank in a 2nd gen case.
