I know what the engines are and everything, but wat exactly is a stroker engine?

 

A stroker is where you increase engine displacement by increasing piston stroke. When you increase stroke, you take the piston deeper in the cylinder bore, which increases displacement. The longer the stroke, the greater the fuel/air charge. Because mechanical advantage or leverage comes with stroke, torque does too.

 

That's why your mom strokes me.

wow thanks, very informational, so a stroker does it have downsides?

 

hahaha very funny lol but hey man cool it this is a forum mustang site, mustang talk only most fo the time so yeah but pretty funny i admit lol

 

Theres alot to the answer to your question. It depends on alot of things, concering advantages/disadvantages


I think you need to do a bit more research on how and engine works and how the principals at hand. There is alot more to making HP than bolting on a N20 set up like in the fast and furious. Samseed pretty much nailed it with that one.

As far as advantages/disadvantages... Strokers typically wont rev up like a short stroke/large bore engine would, but aside from that. There isnt much to be said that falls under the "in general" catagory. The reason being that the specific engine combos will control how affective one thing or another is. Cam specs, bore, stroke, etc all relate to one another and need to be matched accordingly. Thats why making SERIOUS horsepower is left to professional engine builders, who may then write books on proven combos. These guys do alot of experimentation on this sort of thing. Do some reading. Dont be afraid to look up chevy high performance websites. There is ALOT of excellent information on making HP on those chevy sites. You should read them, but first, make yourself VERY familiar with the inner workings on an engine and the different things/principals going on. Theres no simple answer to your question.

if u bore out ur engine, you will decrease its running life a ton. seriously. ur block isnt made for it, but it does provide crazy hp gains.

 

With strokers you may need to worry about the compression height...a stroker's piston is necessarily shorter in order to fit and this can lead to ring land issues. Also, because the piston is shorter it tends to rock in the bore more. As you attempt to increase the stroke of a SB engine, you make the piston travel a longer and longer distance and that can lead to problems in the future (as you can imagine.)The other problem that you sometiems run into is the side loading of the cylinder wall to a greater degree.

 

good info but those problems (mostly associated with a 347 ie. ring land and side loading) haven't been problems for at least 10 years. they are a thing of the past. you can certainly build a stroker to rev as well...my buddy's na 347 revs to 8200rpms.
