Another week has almost reached an end, and Thursday is here once again. That means it’s time for us to celebrate another editorial throwback. Each week, we jump into the way back machine and open the vault that houses our vast collection of articles. In this Throwback Thursday, we’re taking a step back in time to bring you an article that you guys might have either forgotten about, or might not even know exists. Whichever the case, we are certain that you will enjoy this editorial flashback. So, without further ado, let’s take a look back at an article that gives you some much-needed tips when it comes to powering your hot rod – Stroker Engines: The Long And Short Of Connecting Rod Length.
In this article, Eric Labore talks with experts from SCAT crankshafts, Manley Performance, and Lunati, to discuss the ins and outs of increasing engine stroke. For instance, did you know that and engine’s stroke can typically be increased by five-hundred-thousandths-inch (1/2-inch) or more in some stock blocks? That’s a great way to add displacement – and power.

The crankshaft, connecting rod, and piston make up the rotating assembly. Piston compression height, connecting rod length, and half of the stroke equals the deck height in a zero-deck engine.
He does warn that an engine builder must consider all factors when designing a stroker engine for a particular application. While entire books could be written about those factors, the original article focused on the physical (dimensional) and dynamic (operational) properties associated with selecting connecting rod length for a stroker engine.
The original article takes a deep dive into aspects like piston speed, connecting rod angle, piston speed, and design. While an increase in displacement alone will provide for additional power, there are many factors to consider to get the most out of the increased stroke.
It is important to take all aspects into consideration, and understand how one component will affect the overall combination. Rod length alone cannot be generalized as providing a certain change to every engine. Rather, any change in engine performance is due to the connecting-rod length’s role in changing the dynamic properties of the entire combination.
You’ll have to check out the original article to get all the information, but you’ll be glad you did. Since there are probably a lot of enthusiasts either in the throes of or contemplating a stroker build, I thought this a great piece for this week’s Throwback Thursday flashback. So, find out how the gathered information from SCAT, Manley, and Lunati can help your hot rod after you check out – Stroker Engines: The Long And Short Of Connecting Rod Length.
