Planning a stroker build? Here are a few things you should know before you get started.
It wasn’t all that long ago (okay, LBJ was president and Bonanza was a hit TV show so maybe it was a long time ago) that a factory 327 / 350 hp small-block has serious street cred' and Chevy’s 427 making 435 horsepower was boulevard king. Today, it’s a walk in the park to build a 500 hp small-block and a 650 hp big-block Chevy with purely aftermarket parts–but these engines enjoy lots of cubic inches.
An intense look at crankshaft stroke and its affect on mean piston speed, inertia, and controlling the massive, destructive forces at work inside an engine.Engine builders have long calculated the mean piston speed of their engines to help identify a possible power loss and risky RPM limits. This math exercise has been especially important when increasing total displacement with a stroker crankshaft, because the mean piston speed will increase when compared to the standard stroke running at the same RPM.
But what if there was another engine dynamic that could give builders a better insight into the durability of the reciprocating assembly?The video above shows two engines, one with a short stroke crankshaft, and
