Dynomotive Built LS3 Stroker 427 cubic inch, is a long engine made right here in Australia by Team Dynomotive.

In the same way as we deepen the cylinder bore we also increasing the stroke and displacement.  This can be seen in the diagram below where the piston does down further onto the shaft.

By increasing the stroke it boosts the overall power of the combustion cycle.  Consequently delivering more energy to the crankshaft.  Hence resulting in more torque being delivered to the transmission and the vehicle’s wheels.

Diagram 1 – shows the difference between a normal engine and a stroker engine.
