stroker/long rod

[NMBANSHEE]

can some one explain the differences between long rod engines and stroker engines? I understand that a stroker has the rod pins moved, and that the long rod has longer rods on it, just not sure of the performance differences and pro's or con's between the to . Just trying to understand the two better for future mods.

 

Thanks

I'm sure someone else can elaborate, but basically yeah a long rod uses the stock crank pin locations, a longer rod, and pistons that have the wrist pin located closer to the top of the piston (either Wiseco 795 pistons or the "old" way of boring the jugs 80 over and using Blaster pistons for a 370LR). The main advantage is a lower rod angle at the piston, primarily for durability.

 

A stroker uses a different crank layout so the pins are placed farther away from the center of the crank giving you a longer piston stroke, more volume=more power. To get the most out of a stroker you need stroker-specific porting (which if the jugs are already ported for a stock stroke it may or may not work well or at all with the longer stroke), and a means of increasing the stroke (again it can vary between a spacer plate or head mods). Others here can tell ya better than I can.

 

And welcome to the HQ, always good to see someone else from NM heh.

Basically the long rod is for durability and less strain on the crank and doesn't give you any performance gains to speak of...The stroker will give you more power torque than the stock stroke. Like Benbb said, it pumps more air giving more torque, but in return will turn less rpms because of the longer stroke....
