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.
