Okay, correct me where I am wrong but this is what I believe stands true with stroking and displacement. The displacement of an engine is the distance the piston travels throughout the cylinder, from TDC to the bottom of the stroke. When stroking an engine, the only thing altered is the location of the crankshaft pin. This, then would not change the length of the stroke, but simply move the position of the top of the stroke closer to the top of the cylinder, increasing the compression. So why then can somebody stroke an engine from say a 5.0 to a 5.2. Where does this increase in displacement come from?

What changes in a stroker is the throw of the crank, height of the piston, and the length of the connecting rod.

Displacement = Bore x stroke. And +1 to vristang

The height of the piston in relation to the crank?

r.barn

everything changes,

rod length, crank shape, piston height

new crank drops the piston more, you have it backwards in your thinking.

Thanks for the link, and yea i said it backwards rbarn your right, but I had it pictured in my head right. Thanks guys.

strokin is a crank rods and pistons uaually..but u can have a long rod stroker with stock crank.....i think west coat strokers has them...
