Stroker advantage

Everytime I talk to a fellow car guy weither it be a ford Chevy or mopar guy they always talk about their "Stroker motor" I even see it in here alot you see a ton of 408s and other stroker variations. Ever time I talk about my engine build the first thing people say is why ain't you gonna stroke it? So this leaves me to question... what are the power advantages to a Stroker? Other than cubes? For instance take two identical combinations same intake carb, heads, cam, compression, exhaust, bore, pistons everything exactly the same one has a 3.58 the other has a 4" stroke how much more power are we talking? 20hp 50hp.....? I'm just curious and inquiring minds have to know.

Two identical combinations with the only difference being stroke will end up with the same horsepower. The stroker will have more torque but peak horsepower will end up being the same or very close to the same. The extra torque is nice to have in some applications though which is why you'll find bigger engines in heavier cars.

For a performance engine the main reason people stroke them is because it is a cheap way to make more power. If you are building a high performance engine and you need new parts anyway then it doesn't cost anymore to build a stroker. Once you put good cylinder heads and a bigger cam in a stroker engine you'll pick up a lot more power.
