Is 400hp 350 possible?
I have stock 350 that was tpi, wondering if it's possible to get 400hp from it? I want to do carb. Wondering if you guys have any build list or tips for doing so if possible. Thanks

Get close with a big cam and carb intake. Ideally needs head swap like vortecs at a minimum

Yup, what Orr said, I'd keep it EFI and use a short runner intake tho

400 HP 350?
All day everyday with heads, cam, intake and headers.
EFI might prove easier with respect to tuning. A carb will be less expensive (and not that difficult to tune).

EFI: we should be more specific and EXCLUDE TPI from that list. Other forms of EFI, yes; TPI, no.
Stealth Ram, MiniRam, any of the various 4-bbl port EFI intakes, etc.; just not, TPI.
But yes it is very readily done w a carb as well. That's what people did for the many decades of 400 HP 350s that went by before EFI was practical.
