You might be better off asking AI this question to see who's made the most claimed horsepower out of all the data published on the web. But even that should be scrutinized. I vaguely recall somebody claiming 1,200hp with a stage 1 cam and supporting mods. A stage 1! ....and I believe it.

In my personal experience, my Terminator 2 cam appears to be a midrange cam but Jannetty made great peak numbers. 25hp and 100ftlb more torque than a YouTube influencer's peak horsepower cam that was installed by a reputable shop here in the northeast.

So I really don't know. Every time I feel like I have cam knowledge sorted out, someone comes and defies conventional wisdom with unusual results.

If you're looking to throw money at a project, cams are cheap enough to buy multiple so you can experiment. Usually in the ballpark of $500 aside from drivetrain modifications. Maybe buy 2 or 3 top end cams and run your dyno test. Then sell the ones you decide you won't keep at the end of the build.
Thats a great idea... maybe someone can collect 10-12 of the industries best cams, and a few sets of heads, and rent an engine DYNO for a week of back to back testing... that would be AWESOME!!!
