440 or built 360 71 demon

With trick flow heads I don't see any sense in build less than a big if you after serious power. A basic 440 performance build with a trick flow top end got yourself a 600 hp engine. And if you gonna spend the money on a stroker build 500 plus cid out of a 440.

I never understood 408 strokers you spend $7000 on something that is only slightly bigger than the smallest big block (that people build) especially after a rebuild on a 383 gets it closer to 400 cid. And have terrible bore to stoke and rod ratios.

Even just slapping in a 440 crank into 383/400 gets you 431/451.
