360 stroker how much HP is picked up if everything else stays the same?

Freakin A brother! Freakin - A!

Exactly! Purpose and target are all a huge part of the consideration. There's no blanket statements that cover any of this stuff perfectly. Bore, stroke, connecting rod angles (driven by rod length), intake tract length, headers, packaging - it all matters.

And yeah, that would be amazing. There's lots of combos I'd love to play with, even if I wouldn't want to drive them :D

I did kind of conflate the 383v383 and a 360v408 - I was just trying to illustrate with familiar figures.

Given the choice, I think that more bore tends to be better - but that's not always in the cards, and more cubic inches is rarely a bad thing so strokers do have their place.

As others have mentioned though: a stock stroke can still be wicked fast, faster than most people manage to go with a stroker.
