But what is a "stroker" engine?

Be gentle....

 

a 3.1 is an example of a s"stroker motor." You take a "standard" engine and put a crank with a longer stroke in it. That's a stroker in a nutshell.

 

Oh, alrighty, here I was thinking it was some sort of special brand lol, thanks for the info.

 

you idiot
I can't believe you stupid you are

don't know what a stroker motor is


ugh when will these kids ever learn

I mean come on.... stroker... duh


leave the boards and go somewhere else



ok so I'm just razzing you

but yeah a stroker is a motor with a longer stroke as someone else said


the 383 is a common stroker motor

takes the 4 inch bore of a standard 350 and a .030 overbore I think
gets rid of the standard 3.48 inch stroke in favor of a crank from a 400 Small block chevy which is 3.75 inches and puts that in there


so see you gain a .27 inches extra stroke

while overboring is taking some extra meat out of the cyl wall to make for a wider cyl

stroke is the throw of the crank

or from dead center on the crank to the middle of the arms that stick out
that distance is your stroke

hope that helps you a little

 

Ok, so this is kinda on topic for this thread...

Would stroking my 2.8 be worth it? (I've it outta the car and the pan sittin' off it, so putting the new crank on wouldn't take much more effort).

And secondly, how far can stroking go? Like you said, that one is 0.27" (+ 0.30 bore, but yeah) , how far can I take it in my 2.8, and what will it buy me over all?

Lastly, if I decide to do this, where can I find that crank (aka, can I take one outta a different engine from a junkyard, cos I'm on a VERY tight budget here)...

Thanks!

you know what you shoild do? Just go out to the junkyard and pickup a running 3.4L motor and shove it in there, it'll cost you about the same amount of money and you'll get a motor that already has A LOT more power. That's what I think would be worth it.

 

Thanks 2.8boy. I'm in the process of searching/finding a 3.4 now...thanks!
