AI spec cam 
I was just wondering what would "AI" come up with for a nitrous cam setup, I been thinking about doing and these are the results based off the info I provided to it..
Some of the info I gave it... 370 cubic inch, camshaft for nitrous, trickflow 215 heads, 11.5:1 compression ratio, T56 with 3.73 gear ratio etc
What do you guys think?

I think (Any Idiot) would always recommend a low 230's degree cam on a 108° ICL for a 370 just to be safe it works well enough but you can always get a bigger one than that! Or go with a wider split with more advanced and Also 112lsa is really conservative for 370 imo search David Vizard ls cam challenge stuff like that guys are going 250°~260° @0.050" on the exhaust duration NA

I've tried using AI on engines, gears, speed rpm etc and compare it to actual #s and many times it is off. I'll point out where it was incorrect and it will usually then get the correct answers but IMHO always double check it as it still needs tons more work to be reliable IMO

I had forgot to mention before that I called a reputable cam company few years ago and asked for Cam for my 376. I ended up ordering from them a milder custom one because at the time I was trying to be stealthy they wouldn't grind anything wider than a 115° unless you wanted a 119° But the spec that they recommended me was a 230°/242° 112°LSA with no advance... They must have 100 of those stacked up next to the phone lmao
I still find it funny that people use names like "generative" to describe ai, when the most correct terminology would likely be "regurgitative ai". It seems to just take an averaging of the collective stupidity of the internet and puke it back at you, but in an authoritative manner that makes it sound plausibly correct.

Verdad Gallardo Absolutely true, but it is much more satisfying to let an actual person know they are an idiot, than to curse pointlessly at an AI program that has no capacity to give a **** how wrong it is. I'm still looking forward to the programs being put into robot bodies so we can at least beat the **** out of them for fun. Then again, there is the saying that "terminators or sex bots, either way we're fucked".
^^^ That's the post of the year in my opinion & 25+ years of forums.^^^
At least ChatGTP will:
1) Admit when it's wrong if one corners it with facts & proof. It has so far in my experience.
2) In my limited experience it will alter it's opinion or view when proved wrong generally.
Those two factors make that AI shockingly more interesting and dynamic to talk with than a very large number of humans.
The key issue wirh ChatGTP? It is "trained" to handle "issues" by obscuring the truth of it's limitations and mistakes - just like typical "customer service" at a large company when the company makes a mistake. It wants to make you feel good and ofter reassurance because it set up to "be nice" instead of always tell the truth.
Lot of fragile folks with weak personalites out there on the web that really can't handle the truth.
The AI is default designed to try to protect those folks so no harm occurs to their psyche.
One can have ChatGTP to lock "truth & honest first and foremost above all, always as it's governing parameters" into permanent memory this helps reduce some of this BUT it many not kiss *** as much, it may tell you your writing or what ever needs deep revision etc. So only try that at your own risk.
Lot of ❄️ snowflakes ❄️ all flavors, melt if hit with truth.
Never trust it's math, always double check that.
It can deliver some amazingly inaccurate results. Basically, it's like dealing with a promising coworker that is very overconfident in his or hers fairly robust ability.
After dealing with people like that my entire adult life - ChatGTP seems like just another unreliable but good intentions coworker to delegate work to that you always have to check behind.
FWIW

too funny 😁 😂 😀 AI's can be more interesting to talk with much of the time than humans.
The 402, very slow.
Cam will be one of the very last things spec'd by the engine builder & his cylinder friend(s).
Toying with idea of different heads even...so definitely not cam picking time.

Your could stack Oreo in those valve cuts!
Fwiw I've given up on the milder Cam ideas for a while since I've got 14° of overlap @0.050" starting and driving off like stock in my 376" hell now that the ltft have been on for a few days I could barely hear it at idle anymore with the windows up on my way to the dentist yesterday It surprised me how tamer it's gotten on its own since settling in to my first round of tuning on it I didn't think I'd get It close to this smooth with so much overlap but it really drives nicer than I expected it to

I had pretty much the same cam at one time in my old car. It was a custom grind from cam motion, 233/241.4 112.5 LSA 2.5* advance .629/.613 lift. It was a naturally aspirated 346 with trick flow 220 as casts with a fast 102, 1 7/8 long tubes, t56 with 4.30 rear gears. It did not like under 2000 rpm but was fine above that. It had great power from 2500 up. No traction in 2nd gear on street tires and that was with full suspension setup for drag racing.
