Here you go, Piston area and force.

Amount of cylinder pressure psi is how efficient your engine is, they say it's around 1000 psi for a normal average efficient engine to 1500 psi for a efficient race engine to 1600/1700 psi for a highly developed engine like pro stock.

Lbs-ft per cid ranges say from one, I imagine you can go lower but most engines seem to make at least 1 lbs-ft per cid to as high as 1.65-7 lbs-ft is around what the highest NA gasoline engines can do so basically a 1000 - 1700 ish psi, Bmep basically telling the same thing.

So take a Mopar 383 B vs 383 RB same displacements, should be able to build each to similar hp at a similar efficiency level say 1.25 lbs-ft per cid (479) tq, let's say that's around 1250 psi. The B will have more force from the larger piston area but have less stroke to multiply that force to make 479 tq the RB will have less force from it's piston area but will have more of a multiplying effect for 479 tq.

So ideally both of these engines should be able to make basically the same torque obviously there's scenarios where they won't.

Also take a basic 500hp/500tq 408 1.23 lbs-ft per cid now it's possible to get those numbers out of 360 just got to step up your efficiency game to 1.37 lbs-ft per cid and should make the power and torque around the same rpms. Since the 360 has the same bore but less stroke obviously there's a lot more cylinder pressure happening to do so.

For torque amount in the end of the day lbs-ft per cid is more important than how you made that cid.
