20psi stock 5.9 carnage

That figure is an old wives tale. At least the small block Chrysler one. A small block Chrysler will live at 1k HP forever as long as it doesn't get into detonation.

Categorically I agree with you but my original turbo motor made 1222 at the tire with 4 bolt splayed caps. In addition to that My Duster has them too and it made 900 at the flywheel with a 250 shot of nitrous, at that short block is 23 years old with about 400 passes on it.
Pretty hard to argue with actual, factual results like that. So I won’t. What caps are on yours and who did the machine work? Weren’t you using an R Block or Ritter? For some reason I was thinking your red car had an aftermarket block in it.
