One thing leads to another... mean 318?

The larger the stroke over the OE stroke, the larger the displacement. The longer stroke takes in more air and fuel. Thus increasing the explosiveness within the cylinder. This creates more torque and HP.

Therefore, your statement of “Bore only increases HP” is false. Increasing ether will increase displacement and torque to equal HP.

Where you come up with these crazy *** things, IDK!

For your theory to be true the engine with the increased stroke you have make peak power at a similar rpm as the non stroked engine eg... 360 vs 408.

Say for my 360 create engine is suppose to dyno around 400 hp at 5400 rpm, if stroked it to a 402 keeping everything else the same.

It would have peak hp at a lower rpm?
How much lower 400-600 rpms lower ?
more/less ?

If say it's around 4835 rpm peak hp for the 408 both would have the same cid to rpm would be proportional for both engines and both would have similar power give or take the exact effect on those combos.

Not saying it would play out where power is always gonna be identical. True stroke is gonna add displacement there for each power stroke is gonna have more fuel and air there for more torque, But torque is just basically a snap shot of that power stroke, hp is all those power strokes added up. And we all know more displacement with the same top end is gonna mean less rpms, in general but not all cases depending on the combos and situation the rpm loss is gonna be somewhat proportional to displacement differences. Equalling out Hp, some are gonna have a bit of a gain some a loss and some a tie, but I bet that has more to do with cam timing and head ports effect on bore and stroke and rod ratios and frictional hp loss or gain.
