How does cid make power?

$900 going to $4k doesn't sound reasonable just for being Canadian.
Your previous post is the one which turned it into "does it make sense to build a stroker" when you brought cost into it.

You paid $2600 is hard to believe it would a lot more here.

CID by definition makes power. The volume of air expanded is exactly what creates HP. If you start with less air, you have less expansion. Look at it this way: expanding air is work. Work is HP. More air requires more work in order to expand it - which equates to more HP. HP is work, work is HP. It's physics 101.

my OP

"But let me clarify what I mean, I understand if you raise torque at any
Rpm at that rpm hp will also raise. Torque is obviously heavily related to displacement
If I was to say I'm gonna build a 440 without any other info you could ballpark guess how much Torque will be made. Because torque happens in a narrow range for an naturally aspirated engine 1-1.5:1 lbs-ft per cid and for most engines we deal with would be narrower, your not gonna get 550 lbs-ft NA out of a 100 cid engine but could get 550hp since there about 0.5-5.5:1 hp per cid range.

Torque is basically one powerstroke and hp is the sum of all the powerstrokes added up over time.
So obviously displacement has a huge impact on one powerstroke and only has one powerstroke to do it.
The limit on hp is mechanical limitations and ve% limits of rpm so as long you can keep spinning it higher while filling the cylinders you'll make more hp."
