Open Chamber Heads vs Closed Chamber Heads....

If you can build a 500HP 408, you can build a 500 HP 318. If you can’t do the latter, you can’t do the former.

That thread was a waste because the stroker crowd can’t get out of their own way.
And here I'll sit by myself but that's ok, if compression is equal, I'll take the open chamber heads. Just not my experience either, I know of people that lost going to closed chamber heads on motors that spin 7400 rpm's. ET proven.
