Other than short lifespan racing builds, Mike Cotter of
https://naturallyagitated.com/ has a recipe for a 3.4 / 3.5L S54 stroker that reaches 390-400 whp NA, but it'll run you ballpark of US$25-30K. You can get into the 360-375 whp club for about half of that: quality tune + 288/280 cams + stepped headers + extensive exhaust side porting + AEM standalone ECU.
