Legality of crank swaps

The one described as "...over 400whp on a 3.4l stroker s54 that revved out north of 8500. I remember him saying it cost a ton, somewhere near $40k though."? Doesn't sound STU-compliant to me...

All the other non-turbo S54 engines and dyno charts there are indicating 350-ish. At ~3500# sounds like a good STU fit.

The problem is as you get faster weight means less. If you were doing a drag race from 120-150mph would you take the 2000lbs car with 200 hp or the 3500lbs car with 350hp (given they both had the same CoD)? I think the saving grace in all this HP to weight is that a 3500lbs car on 8 inch wide wheels aint gonna stop very well.

Yeah, good luck getting a set of 245/45/17 Hoosiers to last a 30+min race on a 3500lb car with 350hp.

The T2 Camaros did it, and that was with crappy camber too. But they complained a lot about it.
