Stroker or no stroker?
Ok, so I have been thinking about getting my motor built.
I see Livernois has a stroker kit and a non-stroker kit (rotating assemblies) for $2.1k and $2k respectively. It's only $100, but I mean, if I were to opt for one of these kits, would I swing the extra $100? What benefit will I see with the stroker kit? ONLY extra cubes? Or does it actually produce more N/A power?(Or less?) I'm sure I would see more power per psi..
Fill me in.
OR.....
Another route I have been thinking is buying a built short-block or long block and doing the motor swap myself. Probably save on shop labour for building my block?

I'm going to stay with stock displacement. I don't see the need for more cubes with the power i'm making now. If I were building a race car then stroker all the way. Doesn't a stroker decrease the longevity of the motor? I've always heard people say a stroker will wear out sooner, maybe the bearings wear quicker because of the longer stroke.
I don't know what i'm talking about.

Strokers give more lateral force in the cylinder. I'm assuming this is why people generally say that stroker motors don't live as long, whether or not it contributes, I don't really know.
If it means anything, the mechanic I go to doesn't recommend stroking our motors, he's done a ton of builds and is very knowledgable (I trust his judgment). I will more likely than not be keeping the stock displacement as well when I forge which will hopefully be on my own terms

i am planning on staying w/ stock displacement as well. looking into an aluminator bc i may be able to get a good price on it thru my mustang club. i wont be going crazy w/ the power either aiming for maybe 550. my friend who does most of my work doesnt recommend going w/ stroker either, being that my car is 99% street car and not a race car and i plan to keep it for a long while.

IMO the question to stroke can be answered in one simple phrase...
GO BIG OR GO HOME
Specifically, it is a fact that cubic inches increase not only HP but flow but it is also a fact that strokers are more tempermental in that they do not like to spin high and the loss of material makes for a more 'precise' build being needed. It also gets more critical in the valve train when you decrease and increase clearances.
My opinion is that if you want a stroker do it right and go big. Get the big bore block and go for 320+ ci. That is power, flow, and performance worth the price of admission to me.
For what you get for a 'small' stroker (298 or 302) - it is just not worth it IMO.

So I think I will stick with stock displacement at this time as I was wondering the same thing.....I agree there is no replacement for displacement but for the street IMO I just dont need it...thanks modaddict
